Bug 77851

On RH 9.0, using gcc 3.2.2, I invoked valgrind with the command line:
/opt/lcl/bin/valgrind --tool=memcheck --gen-suppressions=yes \
-v --db-attach=yes <my_program>

When valgrind detected an error, it tried to start gdb and got the assertion
failure:

Note: see also the FAQ.txt in the source distribution.
It contains workarounds to several common problems.

If that doesn't help, please report this bug to: valgrind.kde.org

In the bug report, send all the above text, the valgrind
version, and what Linux distro you are using.  Thanks.
