this needs some references to glibc/gtk/python maintainers statements etc.
-lmcheck is AFAIK thread safe in glibc itself.
It seems to me rather that python and/or gtk may have some bugs exposed by
-lmcheck. Could you provide a reproducer (with proper versions of all
components and OS) of the problematic behavior?
Thanks,
