Hi All,
One of our Qt 4 applications that has been running fine for quite some time
suddenly started intermittantly producing the following crash after we upgraded
sip and PyQt:
python: Modules/gcmodule.c:261: update_refs: Assertion `gc->gc.gc_refs != 0'
failed.
Abort
Versions under which it worked correctly are sip 4.5.2, PyQt 4.1.1, Qt 4.2.3
and python 2.5.0. The crashes have been occuring with versions sip 4.7, PyQt
4.3, Qt 4.3.0 and python 2.5.1. We also saw this happen with sip 4.6, but
don't remember the PyQt version number. We're quite confident that we've seen
the crash with both python versions. The OS is Linux RHEL WS 4 (Nahant Update
5) 2.6.9-55.0.2.Elsmp.
I'm not sure whether this is real or not, but I think I can trigger the crash
by moving the GUI window around on the screen before it has completed drawing
for the first time.
Could someone please give us a pointer to where/how we should start looking?
Thanks very much!
Cheers,
Ric
