The complete command line that triggers the bug:
gcc -c -I. -I.. -Ilibavcodec -Ilibavutil -I../../../../zlib
-I../../../../libpng -DHAVE_AV_CONFIG_H -D_ISOC99_SOURCE
-D_POSIX_C_SOURCE=200112 -std=gnu99 -DARCH_X86_32 -DWIN32 -D_WIN32 -mno-cygwin

libavcodec/dsputil.o libavcodec/dsputil.c

The compiler output:
libavcodec/dsputil.c: In function 'put_pixels8_l4':
libavcodec/dsputil.c:1156:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
make: *** [libavcodec/dsputil.o] Error 1


Everything worked fine with GCC 4.5.0 20091029. MPC-HC rev is 1330.

Sorry, I don't know what else I should write here, I hope this helps.

Please attach preprocessed source.  I suspect this is yet another dup of
PR41891.

Preprocessed source added.

Got this but should be normal:
gcc.exe: warning: -pipe ignored because -save-temps specified

I can't reproduce it on i?86-linux even before the PR41928 fix.

Seems to be fixed by side-effect or by weird toolchain. I can't reproduce it
anymore, too. So, I close this bug as works-for-me.
