[Switching to Thread 1090460000 (LWP 8699)]
0x4074f36e in _cairo_pixman_have_mmx () from /usr/lib/libcairo.so.2

Distribution: SuSE Linux 10.0

Probable reason:
Code is compiled with gcc-4.0 and compiled C code of the check probably contains
unsupported instruction.

Additional note:
Starting with gcc-4.1, it is not possible to compile MMX assembly instructions
without -mmmx. It is recommended to compile C and assembly parts in separate
source file.

Comment 1 Billy Biggs 2005-12-31 09:52:32 UTC 
This was fixed for cairo 1.0.2.  Please re-open bug 4414 if there are problems
with 1.0.2 or newer.
