I commented out practically your entire program and it still randomly segfaults.

No difference with 'exp' or 'SuiteSparse_config'. I also tried
replacing -lopenlibm with -lm.
I am able to reproduce the problem with the files below. Julia's
build-dependencies are still required, but not Julia's source.
Contents of shlibdeps.c:
int main(void)

return 0;
}
