The link-time wrapping of malloc is designed precisely so that other
uninstrumented libraries that call malloc by name still get registered in the
libmudflap runtime.  That way, pointers from these libraries may make their way
to an instrumented routine, and be used without error.  Does
MUDFLAP_OPTIONS=-trace-calls produce anything?
