Hello all,
I am getting a crash while reading a PNG file (on the
osgDB::readImageFile() line) in release mode only. This is on Windows
Vista, VC++2005, OSG from SVN (recompiled this morning).
In debug mode, I get no crash, and the image is read correctly. Also,
both the debug and release versions of osgviewer (compiled against the
same OSG libs, and using the same libpng13.dll as far as I can tell)
both load up the image and don't crash. So I'm baffled...
I tried recompiling my app cleanly, no change. I also tried renaming the
PNG DLLs (libpng13.dll and libpng13d.dll) adding ".bk" to see if those
were really the libs it was picking up, and it seems so.
The stack trace I get (although a bit limited, since it's in release) is:
libpng13.dll!675af092()

Not very useful... I know...
Can anyone suggest some avenues for investigation I might have overlooked?
Thanks in advance,
