Yes there is a problem. Its to do with the Montgomery conversion stuff
and BN_RECURSION. A quick fix is to change the #define BN_RECURSION to
#undef BN_RECURSION in bn.h (and bn.org).
A more specific fix is to change bn_mont.c so the BN_from_montgomery()
BN_RECURSION stuff isn't compiled in.
I'll add this to the official tree soon and see if I can narrow down the
problem further and fix it.
