I have noticed an increase in crashes since the new libEQ.a went in. I am not much of a C developer so i hope you all can help me a bit.
I didn't get any core files but i ran in GDB as per the instructions i found via the search feature.
(note to folks like me: use that search button! this is the first time i ever had to post. the answers are almost always there!)
The crash will happen at irregular intervals which leads me to believe that it is related to certian data types. also note that the crash happens very frequently in certian zones such as shadeweaver's thicket and fungas grove, where as other zones have no problem at all.
first some background:
I have the june22 CVS build. I try to keep up to date and have build most versions. i almost always do "make distclean" rather than creating a new directory.
I have double-checked and verified that the only version of libEQ.a on my box is the june 18 version, and md5sum checks out correctly.
I get the "wicked" message about qt ever since qt verification went default, but my installation of qt seemed to work fine in previous versions of SEQ and it does compile without errors when i use configure --without-qt-verification.
so the QT install may be the issue, but it dosen't really seem to be the case.
anyway, attacked below is the backtrace. let me know what additional information i can post to help narrow down the problem.
