PCH failures / ICE: Segmentation fault

[Laurent GUERBY]

Hi, I'm seeing a lot of PCH-related failures that other testers
do not seem to report on CVS HEAD. I'm testing on Red Hat 9 on x86 with
glibc-2.3.2-27.9 with c,ada enabled.

I'm not able to run the compiler on the given failure by hand, I always
get "common-1.c:1:22: common-1.h: No such file or directory" no
matter what I try.

Any idea of what to look at?

Thanks in advance,

Laurent
