................ so it looks as if it didn't get much beyond parsing the .gimprc file.
Let me know if this is any help.
I guess I could get the source and compile with debugging info.

When creating backtraces with gdb, please install the *-debuginfo packages for the program, as far as it is available -- the backtrace is of nu much use without. We'll need the help of the GNOME maintainers here.

It's possible to recompile GIMP without MMX patch or try newer version from supplementary.

I found a compiled version of Gimp 2.9 at ftp.gwdg.de/pub/linux/suse/apt/SuSE/10.0-i386/RPMS.suser-guru/gimp-2.2.9-2.guru.suse100.i686.rpm which I downloaded and tried. It also stopped with an illegal instruction. I then downloaded the 2.9 source and built it on my machine.  This works OK (except that I had to build it without printing since the duistributiion doesn't include all the required gimp-print files and I didn't want to take the time to get them). The Gimp source mentions MMX, 3DNow and SSE.  My K6-2 does MMX and 3dNow but not SSE. Is a determination made at installation time of the processor capabilities, I wonder, and is the rpm thus dependant on the machine doing the packaging? It seems to me that this problem will occur for several Intel Pentium variants too since these also lack SSE (and 3dNow as for that matter).

The problem is caused by our MMX SSE flag settings, which improves speed on MMX and SSE capable processors. We should find a way, either how to auto-detect this feature, or load one of two libraries depending on processor type.

Confirming, that the mmx patch causes the problem.

Michael, could you advice, how to allow MMX/SSE instruction in an assembly code, but don't generate MMX instructions in the C code?

Didn't we have the same problem in mplayer and concluded that this
isn't possible?  If you want to write SSE register constraints for
the operands of asm statements, you have to activate the SSE register
set, but by doing that you implicitely also activate _some_ use of SSE
for GCC (e.g. structure moves and such).

That means the only way is to compile a whole file with -msse (wherein
you can put the sse-requiring assembler), and only ever use functions
of that file if you determine at runtime that you have SSE capabilities.
That's the problem of granularity, i.e. -msse only works file-wise :-(

I have a patch, which fixes GIMP in 10.0. Copiles with MMX/SSE support and starts on K6-2 machine. Should I prepare YaST Online Update or should I fix it only for EDGE/supplementary.

If YOU, the recommended or optional?

Fix it only for the next release.

It seems that version 2.2.9 has this problem fixed:
http://bugzilla.gnome.org/show_bug.cgi?id=308412

I am just now updating to 2.2.10. It has some problems with MMX/SSE code, but -O0 works-around it.

I am closing the bug and expecting, that it's fixed.
