Are you able to share this file? This would help us determine what is causing the crash.
Unfortunatley not, due to corporate policies.
Do you know if the flashcompiler/environment generate any logfiles when publishing?
Build logs or errorlogs?
Is there any way I can find out which step of the build is causing the crash?
I attached a debugger to the process before the crash. But all I can see is that it crashes in a call to memcpy.
Actually the call to memcpy looks a bit odd... It tries to copy 4 294 967 294 bytes.
