@xor_: Basically can't for the life of me get the kernel to coredump automatically. Which is rather annoying, since this appears to be a semi-random crash and a PITA to trigger in any case.
And on top of that, coredumps generated by gcore appear to be borked...
So my cheap workaround would be attaching gdb to luajit in a tmux session, and making sure you're in a position to re-attach on crash (i.e., usbnet). Binaries for all that are available in
there.
(Because *that*, at least, works to get useful stacktraces
).
EDIT: For ref.,
this is the GH issue we're talking about.
EDITē: And my comments on stacktraces were in
this one.
@xor_: Good point on its name, I just fixed that.
