gdbserver multithreaded debugging

["olivier.carmona@ieee.org" <olivier.carmona@tiscali.fr>]

Dear All,

I am trying to use gdbserver to remotely debug a
multithreaded application.

Target is a ARM9, running Linux v2.6.10; gdbserver from the
6.3 release tarball and built on local host.

Local host is a Pentium IV, running Fedora Core 3, gdb v 6.3.

I get a SIGKILL as soon as a thread starts, execution stops
on gdb side, and on gdbserver side it also stops showing a
Terminated: Killing Inferior.

We tried a few things:

- we forced to ignore the SIGKILL and/or the SIG32 signals,

- we forced loading the symbol from shared library on the
host side (thanks to solib-absolute-prefix and
solib-search-path, library copied: libpthread, ldlinux, libc),

- we forced loading a local copy of libthread_db.so (using
also solib-absolute-prefix and solib-search-path),

...,but nonetheless we got not solution.

I don't see this problem while debugging in
non-multithreaded application.

Is there anything I can do to solve the problem I am
experiencing with gdbserver?
