[Bug c/39394] New: gcc 4.4.0 20090306 segfaults at argp-help.c in glibc 2.7 and 2.9

gcc 4.4.0 20090307 segfaults at argp-help.c in glibc 2.7 and 2.9

cpu: athlon64
gcc version 4.4.0 20090307
-march=native and athlon64 used

This is my first post.  I have read http://gcc.gnu.org/bugs.html and I cannot
or am still ingnorant of how to get a preprocessed file.  I added -v
-save-temps to my cflags and I get:

command line option "-.i" not recognized...

I entered cc -v -save-temps ../argp/argp-help.c argp-help.o and got the
following:

In file included from ../argp/argp-help.c:85:
../argp/argp-namefrob.h:80:21: error: mempcpy.h: No such file or directory

../argp/argp-help.c:1717:4: warning: #warning No reasonable value to return

gcc segfaults at argp-help.c

It has been like that for about two weeks.  This machine attempts to compile
gcc-svn and glibc daily.  Sometimes it works sometimes not.

I tested with glibc 2.9 and gcc appears to still segfault.

I don't know if these lines (from my memory) might be useful:

In fuction 'print_header'

I did not find a mce_64.o.cmd in the entire kernel source.

But I just ran the following command for you:
gcc -c mce_64.i -o mce_64.o -O0

Attaching the result of that command as mceError.txt
