Subject: [osg-users] Crash with SVN version of Tessellator
Hi,
I have just updated to the latest revision of OSG and am now getting a crash
when calling Tessellator.retessellatePolygons.
The code in my application calling this function hasn't changed in many years
and has started breaking since the update. I have debugged the issue a little
and the crash is occuring when the Tessellator::endTessellation function is
called. The crash occurs on a call to free. I think I will need to do a full
debug build of OSG to get much further with my debuging (I am using release
with debug info) but a full rebuild will take me a while.
The previous (working) version of OSG I used was revision 11703 and the new
(broken) revision is 11835.
I know al the new GLU code has been added between these revision so I am
guessing that is what is causing the error. Before I go much further I was
wondering if anyone had any info that might help me track down the issue. It
doesn't seem that the required usage of Tessellator has changed but I am hoping
it has so I can simply call some different methods to fix the issue.
Cheers,
Brad
