Isn't it telling you?

You should be able to look that line up: `(function.cpp:11924)`. I suppose
that's a cython generated file, so the context there will tell you which
function this is in the corresponding `function.pyx` file.
I have no experience with valgrind myself. However, I think Python's
memory management can confuse valgrind quite a bit. I was actually more
hoping for a "double free" or "access to freed memory block" type error
(i.e., illegal use of a pointer value.)
It may well be that my SIGILL is indeed a matter of mpfr on Corei7
compiling to something that's too fancy for valgrind and not a pointer to
an error.
