Bug#519221: libpixman -- bug recently submitted related to your patch

Thank you for your response.

I have compiled the latest git of pixman with the --disable-sse2 flag
and it works perfectly. The problems are gone when I disable that

Here is some more information about my system in case any of it is helpful:
- AMD Opteron dual-core CPU, 2.4 GHz, supporting with flags: fpu vme
de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36
clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm 3dnowext
3dnow pni lahf_lm cmp_legacy.
- I am running a 32-bit OS, although the CPU supports 64.
- ATI X300SE PCI-E video card, using the free and open-source radeon
driver for 3D acceleration. I believe this driver only supports some
of openGL 1.2.
- Kernel 2.6.26
- 1GB ram
- Terminal emulator is konsole from KDE 3.5; pseudo-transparency is
turned on (that is, it paints the desktop background as the terminal
background to make it "appear" transparent)

I hope we can find the source of this problem. :) Is it possible to
take out only some of the sse2 modifications so we can determine which
optimization is causing problems?

Thanks for your time,
