 Thanks, but I need a testcase to have a hope of fixing it.

In the continuity of PR: c/7138: gcc-3.2 failed to compile kernel, I try to have a look in the preprocessor output with -dM -E option which do "Segmentation Fault" as follow:

palx2000:/Develop/parisc-linux/src/linux/arch/parisc/kernel# gcc -dM -E -D__ASSEMBLY__ -traditional -D__KERNEL__ -I/Develop/parisc-linux/src/linux/include  -c -o pacache.CPP pacache.S
In file included from /Develop/parisc-linux/src/linux/include/asm/assembly.h:31,
                 from pacache.S:44:
/Develop/parisc-linux/src/linux/include/asm/offset.h:3: unterminated #ifndef
cc1: internal compiler error: internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

Here is also some additional more expert comment:
"The '-c' shouldn't be there but cc1 shouldn't ICE on an unterminated #ifdef.
Is the #ifdef actually unterminated?  Would you file a PR on this one as
well?

I'm also seeing a problem with the preprocessor on the vax :(
