Fixed in mainline and 4.1 branch.

As far as I can see, the ICE reporting a Broken pipe error can only happen if
the gcc driver itself is invoked with SIGPIPE blocked. That is not the normal
case.

Will not be fixed in 4.1.1; adjust target milestone to 4.1.2.

With patch foo6.patch, I get:

gcc -c voodoo.i -o aaa/t.o -pipe
Assembler messages:
FATAL: can't create aaa/t.o: No such file or directory
src/vidhrdw/voodoo.c: In function ‘voodoo_start’:
src/vidhrdw/voodoo.c:262: internal compiler error: Broken pipe
Please submit a full bug report,
with preprocessed source if appropriate.
See URL:http://gcc.gnu.org/bugs.html for instructions.

Although it does not hang, the error message is a little confusing. It should
not be internal compiler error.

We are hanging in:
#3  0x0805c75a in pex_unix_wait (obj=0x9bc7948, pid=23370, status=0x9bc7848,
time=0x0, done=0, errmsg=0xfe00, err=0xfe00)
at /home/peshtigo/pinskia/src/gnu/gcc/src/libiberty/pex-unix.c:470
470   if (pex_wait (obj, pid, status, time)  0)

CCing Ian based on that he rewrote pex_* for 4.1.0.
