With the Xcode 2.4 release, the nan_inf_fmt.f90 testcase in 
gfortran.fortran-torture/execute
has begun to segfault on Darwin PPC at both -m32 and -m64. The backtrace from a
segfault
is...

Starting program: /Users/howarth/testdir/nan_inf_fmt/a.out

It has been suggested on the list that this might be due to size mismatch and
that
the new Xcode 2.4 is exposing a latent bug in libgfortran...
