I don't know the code of mpfr. It could use __builtin_strlen for stuff like parsing numbers etc. However, the builtin_strlen code looks OK and hasn't been causing trouble elsewhere. So I guess that it just runs on broken data and then causes a buffer overrun. In other words, the actual bug is somewhere else -- a quite common scenario for segfault class of bugs.
