Hi all,
there have been occasional bad crashes of an application in whose
development I'm involved in (Padre). With your generous help, I managed
to build a debugging perl+wxWidgets+Wx combination and finally obtained
a backtraces for such crashes. I always suspected a combination of
ithreads with wx to be the culprit and unfortunately, it turns out I was
right. It seems to happen only when a background thread is joined.
Specifically during the resulting cleanup. I'm wildly speculating now:
Maybe some of the Wx objects with underlying non-ithread-aware C++
implementation are being cloned on thread creation and dubiously freed
on thread exit. Or maybe it's due to Thaw being called on a window that
wasn't Freeze'd (see backtrace).
You can find an example backtrace with some additional debugging info here:
http://padre.perlide.org/attachment/ticket/287/backtrace
I'm unsure how to proceed with debugging these issues. I'm out of my
depth, unfortunately, and would really appreciate any help.
Does anyone have any pointers on how I should go about finding the cause
of this? Could you help if I provided more info? Right now, I'm able to
conveniently reproduce that crash. I will try not to recompile or
overwrite any part of the setup for a while in order to keep it that
way. Please help.
Best regards,
Steffen
