And that worked; it is a kludge since I dont have the latest version, but at least I can access my books !

The kludge is no longer needed, just update your Mesa package and rune the latest Calibre.

Still just as broken as before. Keeping 4.9.1 as it still works.

Calibre is the only program doing this too.

malloc(): corrupted top size
Aborted

Dear Kovid,

any Calibre version newer than 4.9.1 and including the latest 4.14.0 Linux 64bit binary still does not work here (PCLinuxOS and mesa 20.0.5). I noticed that I get different error messages when running calibre from the user account:
malloc(): invalid size (unsorted)
Aborted

while I get this error when running calibre from the root-account:
double free or corruption (out)
Aborted

The error may indicate that something is deleted which was already deleted before or something that wasn't allocated. Again, 4.9.1 still works fine so something in the more recent Calibre version must have changed with maybe pointer allocations? Any idea how to fix this issue?

calibre is mostly python, there are no pointers. What has changed is an updated version of Qt, which is incompatible with something on your system. Sadly there is no way to really know what that might be. You can try to get a backtrace to see where the crash occurs, google how to get a backtrace for your sitro.

I have today installed the latest version, it still crashes with
ron@localhost:~ $ calibre
malloc(): invalid size (unsorted)
Aborted

I attach the gdb backtrace.

@rolgiati: still the same backtrace

Dear Kovid,

you say "the problematic malloc is still happening inside libGL, from the driver, which is in turn called by the Qt code to initialize the frame buffer context."
Maybe so, but can you explain why on the very same system (same libGL and QT), starting Calibre 4.9.1 works just fine while starting Calibre version 4.10 and later will result in the crash described? My only explanation is that something within Calibre has changed since 4.10.0 causing this crash, or?

Reading your answer again, you mean you have an updated QT version in 4.10 + compared to 4.9.1, and this may cause the crash, correct?

yes .

After a change of mother board and graphic card, but still same OS I installed the latest version to see if the hardware upgrade had improved the situation.
It did not ;-3(
So I reinstalled the 4.9.1 version, running as root

calibre-uninstall && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin version=4.9.0

Alas, when I tried to launch calibre again, I got the dreaded message:

 $ calibre
malloc(): invalid size (unsorted)
Aborted

I notice in the install output a line:

Using previously downloaded calibre-4.17.0-x86_64.txz

Would that be the problem ? Should that not refer to calibre-4.9.1 ?

Interestingly, locate locate calibre-4.17.0 does not find anything...

[kovidgoyal]

Try deleting /tmp/calibre-4.17.0-x86_64.txz

[rolgiati]

Thank you for your quick reply, and the the advice; I went to /tmp/calibre-installer-cache as root, and deleted both calibre-4.17.0-x86_64.txz and calibre-4.17.0-x86_64.txz.signature.

Then launched the install:

# calibre-uninstall && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin version=4.9.0

Seems that in spite of being asked to use 4.9.0 it uses 4.17.0

Get the same result trying with 4.9.1

[kovidgoyal]

Works for me:

wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin version=4.9.0                               *

[rolgiati]

Solved, sort of:

Your reply gave me an idea.

So as root, I first ran
# calibre-uninstall

Then when the uninstall had finished, still as root I ran
# wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sh /dev/stdin version=4.9.1

and this did download and install the right 4.9.1 version.

Now, why this did work I leave to your sagacity ;-3)

[rolgiati]

Next time I have to do this i'll try to add a sleep 120 && berween the uninstall and the wget, and let you know.

My distro (PCLinuxOS) has now updated mesa to the 20.1.1-1 version, and calibre 4.19.0 runs without problem.
