 The problems started when compiling blender 2.40, they persist with
 blender 2.41.

Just for the record, the problem persists when trying to build blender
2.42 using gcc-4.1_4.1.1-8 on mipsel. I don't know about mips yet.

Additionally some other ICE crept up on m68k, I've contacted the
buildd maintainers in order to solicit further info for a bugreport.

Cheers,

blender 2.41.
I'm at a loss on this. To me it looked like a compiler bug, so I tried
lowering the optimization to -O1, but this didn't help. Also my
google-fu failed me and I didn't find anything remotely helpful on how
to best proceed. I'd love to report this as a bugreport against gcc,
but lacking access to a MIPS machine myself (at least one where all
Build-Dependencies are present, and it'd be rather complex to strip
down the offending function so it could be tested on casals or vaughan)
I cannot provide any preprocessed files that trigger this bug.

So, any pointers, please...?
