Unfortunately no, I haven't got -fvisibility on the command line.

I even tried to explicitly disable it with -fvisibility=default

No luck.

Curiously enough the libmudflap code explicitly refers to
   extern int main();
in gcc/libmudflap/mf-runtime.c
int
__wrap_main (int argc, char* argv[])
{
   extern char **environ;
   extern int main ();
   extern int __real_main ();
   static int been_here = 0;

The object code under test has a "main" defined, but once it's linked... it disappears.

Weird.
