>Description:
The following causes infinite recursion within libgcc.

float
foo ()
{
  return 1.23;
}

int
main ()
{
  return foo ();
}
>How-To-Repeat:
Simply compile and run it on the simulator.  Compile options do not matter unless -O3 is specified, in which case the functions in the example are inlined.
>Fix:
This fixes the problem, but I am not sure if this is the right way to go about it.
