That was with gambc40b12, sorry.  Beta 13 is a mess.

First I built it with CC='gcc -m64' and got the following warnings.

os_dyn.c:258: warning: 'NSIsSymbolNameDefined' is deprecated

It then segfaulted in my bignum tests, so I did a make clean and  
reconfigure with -g and got

So, for some reason, "make clean" removed the .c files.  Wow.

The crash occurs in bignum.make, at

Program received signal EXC_BAD_ACCESS, Could not access memory.

Hmmm.
