Valgrind doesn't complain on FreeBSD.
Did you manage to fix your mpfr issue?

No problems either on x86-64-linux (w/ MALLOC_CHECK_, MALLOC_PERTURB_ but also
with valgrind).
Given that the code is rather standard, it must be either a local problem or
one of the nasty race-condition bugs, which only trigger very rarely.

It seems to work now, no free() error messages. Maybe you can close the issue.

Again, thanks for the bug report. This may also have been
fixed by Mikael patch. I'm closing this with a WORKSFORME
tag. FIXED might also apply.
