Also with the cube demo?
If it happens with the cube demo, please provide a log file at the TRACE level. It shouldn't be too large for the cube demo.
If the crash only happens in another application, please try the generate a log file at the DEBUG level...

Thank you!
@gid15: when I build (only tested on 64-bit):
1) without SSE, i have no crash with TOE, 007 and PBP
2) with SSE4.1, i have a crash
3) with AVX2, i have a crash

If i disable jitasm on vertex decoder, those crashes are gone.

The reason is there is a load instruction which tries to use a 64-bit address as a signed 32-bit offset which is alway truncated. As long as this address ranges between 0x00000000 and 0x7FFFFFFF, it works but outside, chance to get an exception. So we'd better to disable jitasm vertex decoder until this issue is gone. This is my fault, i added some functions in jitasm to be able to pass immediate address to a load/store instruction but it happens to be more complicated to do in 64-bit because of that 32-bit offset limitation Sad.

P.S.: oh gosh, I just forgot to answer the right topic: jitasm-ed vertex_decoder was in use when __use_sse__ >= __use_sse2__ when I had a phenom X4 but this decoder now uses "dpps" which is a SSE4.1 intruction !
