#55077 — Using GNU libc mtrace/muntrace via ctypes?

SubjectUsing GNU libc mtrace/muntrace via ctypes?
Message-ID<mailman.487.1380552023.18130.python-list@python.org>
I'm getting an error in certain situations which leads to this message:

*** glibc detected *** /opt/TWWfsw/bin/python: corrupted double-linked
list: 0x0000000007952420 ***

Valgrind hasn't been any help. I'd really like to avoid recompiling
Python, as that might just move or obscure the error. Might it be
possible to enable the GNU libc malloc tracing via ctypes?

Thanks,

Skip
