seen with current 4.1 and 4.2 branches, not seen on the trunk.

While trying to compile the 2.6.23-rc4 snapshots from buildserver.net on hppa,
gcc went in some kind of endless loop over the following command

hppa64-linux-gnu-gcc-4.1 -Wp,-MD,fs/ocfs2/.alloc.o.d  -nostdinc -isystem
/usr/lib/gcc/hppa64-linux-gnu/4.1.3/include -D__KERNEL__ -Iinclude  -include 
include/linux/autoconf.h -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs
-fno-strict-aliasing -fno-common -Werror-implicit-function-declaration 
-fno-cse-follow-jumps -Os -pipe -mno-space-regs -mfast-indirect-calls
-mdisable-fpregs -ffunction-sections -march=2.0 -mschedule=8000 
-fomit-frame-pointer  -fno-stack-protector -Wdeclaration-after-statement
-Wno-pointer-sign  -Ifs/ocfs2 -DCATCH_BH_JBD_RACES  -DMODULE 
-D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(alloc)" 
-D"KBUILD_MODNAME=KBUILD_STR(ocfs2)" -c -o fs/ocfs2/.tmp_alloc.o
fs/ocfs2/alloc.c

this is for the parisc64-smp flavour, all other flavours seem to build fine. I
had no time yet to investigate the differences.
Building with -O0 seems to work, -O1/-O2/-Os all show the bug.

This sounds like an exact duplicate of PR 31944 which was just fixed.
