Problem with g_signal_has_handler_pending causing an Access Violation in Windows

[Ari Jolma <ari jolma tkk fi>]

Hi,

I've got an annoying problem with GTK with Perl in Windows. I'm using 
the precompiled GTK DLLs, but Perl and my own code I've compiled with 
mingw. Sometimes in the Perl's last global destruction phase, Windows 
(actually the dependencywalker tool that I use) reports an "Access 
Violation" in libobject-2.0-0.dll and the address seems to point to the 
g_signal_has_handler_pending function. This problem is a bit evasive 
(but when it appears it persists) and I've never seen it in Linux with 
the same application. I tried to debug it by compiling my own version 
(with msys) of libobject-2.0-0.dll (from 2.12.11 sources) where I added 
debug statements, but I've not been able to reproduce the problem so far 
with that dll - the application works fine and it does not seem to call 
g_signal_has_handler_pending ever.

The problem is only annoying and it looks bad when Windows brings up 
this error box when the application is closed but otherwise it is not 
harmful.

Would anybody have any ideas what's causing the problem and/or how to 
debug it?

Thanks,

Ari
