I just compiled the latest SVN 25439 on linux in 64-bit and when I try to run mess n64 -cart sm64u I get
Ignoring MAME exception: n64_rdp::DrawTriangle: span aux buffer overflow
terminate called after throwing an instance of 'emu_fatalerror'
I tried the same cart on revision 25399 (the most recent previous build I had) and it worked as expected.
I hope this isn't annoying; I'm just trying to be helpful. I'm very excited about the speed improvements! Very glad to hear CEN64 is sharing with MESS!
Just saw Just Dessert's post on the SVN build thread. I did build it with ARCHOPTS set to core2 and I do have a CPU with SSSE3 (at least, I see it as a flag in /proc/cpuinfo - Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz).
I'm recompiling now with USE_SIMD 1 in rsp.h.
Recompiling with USE_SIMD 1 makes it work as expected!
