[Sigil 0.8.3] Issue

[Gunnerp245]

Downloaded and installed the 0.8.3 release. Upon execution, however, the program errors with the following:

Hi,
The faulting module name is called StackHash according to the info you posted but Sigil has no module named StackHash nor is there any code using that string in the Sigil source code repository.

Fault Module Name: StackHash_9f59
Fault Module Version: 0.0.0.0
Fault Module Timestamp: 00000000
Exception Offset: 04c4d1c0
Exception Code: c0000005

So could this be related to a virus protection program? My search on google for "StackHash fault module" indicates that it is indeed an anti-virus related error and that there are DEP setting on Windows to tell the antivirus program to stop interfering.

For what it's worth; I just installed 0.8.3 on the exact same OS -- Windows Vista Home Premium SP2 (32-bit) and experience no issues like that.

@KevinH / DiapDealer

Responses must appreciated.
Attempts to set an exception in DEP results in;

"Data Execution Prevention
! This program must run with data execution protection (DEP) enabled.
You cannot turn off DEP for this program."

Additionally, I have no issues running 0.8.1.
Also running;
McAfee Antivirus Plus
CCleaner

Hi Gunner245,

There should be an "exceptions list" or "ignore me" list of some sort with your anti-virus software. Try googling "StackHash fault module" and seeing if there is some other way to deal with this. It truly is an issue with your anti-virus software.


BY the way, make sure you have verified the sha256 sum of your download to make sure nothing nasty go attached by any issues on your own machine.

Here they are directly from the site:

Run a sha256 sum tool over your downloaded binary and it should exactly match one of the above. If not, try redownloading a fresh copy. There are online sha256 tools that will run the check for you if you do not have an executable.

Apache recommends this online sum tool:

Windows shows StackHash_HHHH as the faulting module as a fallback when it cannot identify a loaded module at the memory address of the instruction that was being executed when a DEP error is trapped. A hash code computed on the contents of the instruction stack is just a shorthand way of identifying what was on the address stack when the fault occurred--if multiple crashes occur with the same hash, then it points to a possibly deterministic and reproducible error. These sorts of errors are caused by the same sorts of faults that produce other memory addressing faults--it can be unstable or faulty hardware, or a host of programming or data errors, any of which can cause the CPU to try loading an instruction from a bad address.

I've only ever run DEP in it's default mode: which is to only check essential Windows programs and services. I have no idea if there's code in Sigil that DEP would flag if it was turned on for all programs. There was memory corruption fixes in 0.8.3. Perhaps there something there DEP doesn't like (when it's modified to check all programs). I've no idea.

Hi JSWolf,

Thank you for that description. I did not know that. How does anti-virus software actually force close a program it does not like? Does it inject code into the stack to force a segfault or abort? It must be related as every Google search I did seems to point to this type of error happening with anti-virous software of some sort?

I am not a Windows person at all. Any Ideas of how to track this down and determine if it a conflict with some Anti-Virus software?

Thanks,

KevinH

Are the various drivers (including Video card) current on your system?

Hi,

Interestingly enough the StackHash_9f59 string is findable on google and exists for Windows Vista Service Pack 2 and was related to running MySql back in 2009. The hash value and the first two lines of Additional Information match byte for byte with the error reported here. The bug reporter could not find any reason for the bug. Neither could the MySQL developers. But funny enough the user did find a workaround:

"Suggested fix:
If you change the Appearance Settings to anything except "Windows Aero" OSS WB will start without error."


Another program FreeCAD which is a Qt program had a report in 2011 with the exact same StackHash_9f59 and all 4 lines of Additional Information were byte for byte identical. Again this was from a Vista user and that user fixed it by updating his ATI driver!


So it appears to be a Vista problem related to graphics in some way since the exact same stack hash has shown errors in the past under completely different executables.

Sorry, I can't really help more, other than to say, the likelihood of the Sigil code base with the latest compilers in 2015 exactly matching a problem in 2011 or 2009 seems quite remote, meaning that the issue if probably something else on your system and not Sigil.

Hope this helps,

Kevin

Checking for updated ATI drivers.

Updated with the latest ATI driver found at the Toshiba website...same error.

Ran sfc /scannow. It reported fixing 'some' errors; however the log report is locked and unviewable... Still get the same error.

Hi,
Have you tried any of DiapDealers unofficial builds. Yes they are typically for older versions of the OS but should work just fine on your machine.

Those builds also use a different flavor of Qt5.4.0 than the official release does (Angle vs OpenGL desktop).

Worth a shot.
