Thanks for the report. Could you possibly attach the preprocessed source file
that triggers the internal compiler error?

I compiled again disabling Altivec optimizations and it worked :)
$./configure --disable-altivec
[...]
$make
[...]
$ ./ffmpeg

At least one output file must be specified
I hope there are not so much optimization issues by using this ffmpeg...
Anyway, I guess this bug should be solved...

------- Comment #5 from rguenth at gcc dot gnu dot org 2009-04-21 13:55 -------
Reducing very slowly ... which makes it sound like a GC issue.
But, confirmed with the original testcase and a cross-compiler. Fails on
the 4.3 branch with -O3 -fno-math-errno -maltivec -mabi=altivec -g, works
for me on the trunk.

Indeed. Fails with --param ggc-min-expand=100 --param ggc-min-heapsize=131072,
works with --param ggc-min-expand=100 --param ggc-min-heapsize=0.
Didn't we have a ppc GC problem somewhere? With always-collect we get
./cc1 -quiet -o /dev/null bmp.i -O3 -fno-math-errno -maltivec -mabi=altivec -g
--param ggc-min-expand=0 --param ggc-min-heapsize=0
libavcodec/bmp.c: In function 'bmp_decode_frame':
libavcodec/bmp.c:307: internal compiler error: in tree_node_structure, at
tree.c:2241

GCC 4.3 has not supported for some time now, and FFMPEG currently builds
successfully on PPC Linux with GCC 4.5 (see http://fate.ffmpeg.org/).
Please close this bug.
