Description of problem:
This applies to gdb 5.3 (installed from source) -- this version was not proposed in the selection list!!
I am experiencing a problem similar to that described as resolved in bug 31712. This happens either with and without Electric Fence (2.1). It occurs when I 1) receive a signal due to some bug, and 2) when I try to obtain
I am running a 2.2.13-7mdk glibc2.1.3 system; any ideas what this can be due to?

Can you send a transcript of a gdb session where the error occurs?
Can you also try a newer rpm, there is one based on gdb-5.3.90, and seeif the
problem still occurs?
Could you please answer Elena's query above? Have you tried using a later
release of glibc? There were some fixes made in the libthread_db area which is
crucial for gdb to debug threads.
Sorry, this reached me during my vacation.
No, I did try another glibc. I have the latest version available for my (in binary installable), and won't take the risk to build one myself. :(
Ok, could you give us a transcript of a gdb session with
"set debug lin-lwp 1" set and whatever source you can give
us that generates the error. It would also be helpful to
have the updated version numbers of the various components you are
currently using (kernel, glibc, and gdb).
Red Hat Linux is no longer supported by Red Hat, Inc. If you are still

current Fedora Core release or Red Hat Enterprise Linux or comparable.
Some information on which option may be right for you is available at
