I've seen similar things happen on my 3.0-RELEASE system.  If all running
programs can remain paged in, the system runs fine.  Once processes start
getting swapped out, I get corruption when pages are paged in from swap.
Header files get an occasional random character changed in them,
shared libraries crash with SEGV errors (once libc.so became
'corrupted' and I had to reboot), builds fail randomly and the system
basically goes into chaos and occassionally crashes.

Since there's no a.out gdb compiled I went to compile the latest gdb with
a.out support, but it blew up in syntax errors.  What version of gdb will
actually build on 3.0 with a.out support so I can debug my crash dumps?
