gdb cannot read core dumps on newer kernels

["Christian Groessler" <cpg aladdin de>]

Hello,

I'm having problems with core files generated from 2.1.131 kernels (2.0.35
do work):

[chris@alpha:~]$ ./segv
Segmentation fault (core dumped)

[chris@alpha:~]$ ls -l core
-rw-------   1 chris    chris      172032 Dec 30 17:59 core

[chris@alpha:~]$ file core
core: ELF 64-bit LSB core file Alpha, version 1, stripped

[chris@alpha:~]$ gdb segv core

This GDB was configured as "alpha-redhat-linux"...
Core was generated by `./segv'.

#0  0x0 in ?? ()
(gdb)

It doesn't find the register values in the core file.

I also tried recompiling gdb, but it doesn't work either.
Does anybody have an idea on how to fix this?

regards & thanks for your help,
