CVS1902 preprocessor problem on Linux/ia64

[Jes Sorensen <jes at linuxcare dot com>]

Hi

While trying to bootstrap today's snapshot (Feb 19, 2001) under
Linux/ia64, I am having problems with the pre processor (I asume)
segfaulting.

Ie. if I run a compile on some of the files with -O2 it fails, On the
other hand it works if I run gcc with -O1 or if preproces the file
manually with -E and then compile the resulting output manually.

Since I can't really provide temp files that will allow you to reproduce
this bug I was wondering if there is something else I can do to make it
easier for you to track it down?

The command resulting in the crash is attached below.

This problem did not occur with the last snapshot I compile, 20010214.

Jes
