GDB enables mcheck if available, unless Python with threading support is
built in (which most distributions do). I've proposed to deprecate
mcheck in glibc, with a goal towards eventually replacing it with stubs
unavailable to newly compiled programs. GDB would still run (and
compile), albeit without mcheck support.
I see two bug reports about issues discovered with mcheck, so maybe it
is useful.
Could you move mcheck in-tree? Then you'd be able to enable it
regardless of Python threading support.
