#120 Illegal instruction on SSE2 fwiConvert_32f8u_C1R

[Andrew Straw]

I just tested one of my libraries on a Pentium 4 computer running Ubuntu 8.04 and framewave svn r469. This computer does have SSE2, as seen in the output of /proc/cpuinfo. Anyhow, I received the following traceback in gdb. I can debug this further, but I'm a little short on time right now, so I thought I'd file the bug in case anyone has any ideas in the meantime.

Program received signal SIGILL, Illegal instruction.

Hi Andrew,
We could not reproduce the issue, Can you please execute the attached c file and tell us the output. Attached c file just calls one sse2 intrinsics, this is to confirm if the problem is with FrameWave
