Patch

Bill,

can you please try the attached patch?

It adds a check in find_array_section to prevent interpreting an mpz
non-integer constant as an integer.  This should provide a cleaner
error recovery.

Regtested on x86_64-pc-linux-gnu.

And thanks for the traceback.  valgrind did not show anything.
