DevIL's 1.7.8 ./configure script enables SSE, SSE2 and SSE3 instructions if
supported by the compiler and unless such instructions are explicitly disabled
by --disable-sse3 etc. There is not run-time check for CPU support when using
these instructions - in fact it adds the -msse3 compiler option.

SSE3 is not universally supported in 32-bit x86 CPUs and using affected
functions such as ilConvertImage() may result in the application being
terminated with the SIGILL signal on such CPUs.

Re-building DevIL without SSE3 support fixes this bug - disabling SSE2 and SSE
should also be considered.

There is also an upstream DevIL bug report at

Additional info:
This bug is also found in many other Linux distributions' DevIL packages:
- Gentoo (fixed):
- Debian (open since over a year)
- Ubuntu (open):
- openSUSE (open):

I've disabled sse3 instructions for 32 bits CPU, it should be enough, as sse2 are available since 2000 (2004 for sse3).
