Description Alan Swanson 2012-04-22 15:54:24 UTC

While testing the Arx Fatalis open source port Arx Liberatis, I found a problem with the Devil library causing illegal instruction segfaults.

Devil compile tests the -msse, -msse2 and -msse3 options but does no runtime test and hence is always built with them if GCC supports them! There is no actual SSE assembly code or defines in Devil itself.

I would suggest disabling these tests and leaving users CFLAGS/CXXFLAGS to decide whether to use any SSE compile options. Please add the following to econf;

--disable-sse
--disable-sse2
--disable-sse3

I'll raise a bug on the Devil bug tracker.

The use flags should be good enough.
