Using both version 1.46 and 1.5 I am running into an occasional crash while loading images using imageFileFormat::loadFrom() . It looks like there is a corruption problem corrupting memory in either the heap or statictly allocated memory. It happens only in a release build if OPT:/NOREF is set. This project setting in the linker tells it to not remove unreferenced data/code. It appears that this setting may just move the problem somewhere else such that the symptom does not appear. I would expect it to be worse when I build with OPT:/REF but it seems to work fine.
I have a simple project that loads a single png multiple times and it seems to crash after a different number of times depending on the day, but it always crashes. I can provide that project for debugging if it would help.
