[Bug c/41955] New: ICE compiling today's linux kernel git snapshot

[chris2553 at googlemail dot com]

Trying to build today's linux kernel development snapshot with gcc-4.4-20091103
snapshot, I get:

  CC [M]  fs/ext4/mballoc.o
    CC [M]  fs/fat/namei_msdos.o
    fs/ext4/mballoc.c: In function 'ext4_mb_add_groupinfo':
    fs/ext4/mballoc.c:2230: 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[2]: *** [fs/ext4/mballoc.o] Error 1
    make[1]: *** [fs/ext4] Error 2

The build completes successfully when I revert to the 20091027 snapshot of gcc.

I have to go to out now so just a teads up to start with. I will get more
diagnostics tomorrow.

The preprocessed file that triggers the ice

Had to compress the file because bugzilla reported that it was too large.

I think it's a duplicate of PR41935 that has already been fixed today.
Could you please try today's sources (or apply the patch mentioned in comment
#7 of PR41935)?

Yes, that seems to be it. With the patch applied, the ICE is gone and the build
completes. Thanks. Should I mark this report as fixed?
