Addendum to previous report

Hi. My previous documentation bug report concerned mpn_tdiv_qr
requiring the top limb of the divisor to be nonzero. Indeed, the
documentation at the top of the source code tdiv_qr.c states this,
but the TeX documentation does not. Conclusion: the previous "bug
report" is a "documentation bug".

I ran into a similar issue with mpn_get_str, which appears to have a
similar requirement. This appears to be discussed neither in the
source nor in the TeX documentation. I don't know for sure that this
is the nature of the problem, but as soon as I started searching my
limbs for the largest non-zero limb and passing in the minimal count
to mpn_get_str, my program stopped crashing.

As before, this was GMP 3.1.1.
