Comment (by cdavid):

 The fact that the problem happens on pentium 3 is an indication that it
 may be a SSE problem. Illegal instruction often means that the binary uses
 an opcode not understood by the compiler, which is obviously the case if
 you use SSE3 instructions on a a CPU without the SSE3 set.

 I attached a simple python script you can run to check the binary:

 python x86analysis.py NDIMAGE_PATH

 It will disassemble the binary and look for SSE and SSE2 instructions.
