SuSE Linux and core files

[nick]

I have two problems with gdb under SuSE 6.4 running on x86s.
Which is baffling as this must be a common platform.
Both the gdb from SuSE CDs and one built locally with simple ./configure 
behave the same.

Reports below from local build.
More than willing to re-build for CPU type in use, and/or rebuild 
kernels to match GDB if that is what it takes.



1. I have never been able to get it to diagnose a core file on linux.
   (Used to work fine on SPARC/Solaris).
   e.g. on Athlon

2. When used with threads it blathers on about unknown signal:
