Do you get a failure with a C testcase equivalent to Steve's fortran one?

Does the GCC testcase gcc.dg/torture/builtin-math-3.c pass for you?  That one
tests for erf(1.0) and erf(-1.0).  I'm curious if it's the value 1.5 or whether
having it come from the fortran frontend (or either/both) which is the bug
trigger.
