You should try the same using some other shared library, to see if
this is specific to gmp.  I already advised this.

You can create a fresh shared library to try with

        gcc -shared foo.c -o libfoo.so

and run it from a mainline with

        LD_LIBRARY_PATH=. ./bar

You can add "-g" to the compiles to get better info from gdb, if it
dies, including building gmp with CFLAGS=-g to see what happens in
that case.
