[Bug fortran/19546] New: Internal subroutine setting function return value gives internal compiler error

[nburrell at unc dot edu]

With gcc 4.0.0 20050119 
on powerpc-apple-darwin7.7.0 (Dual G5 mac running Mac OS X 10.3.7) 
and GCC configured with: /Users/nburrell/Desktop/gcc-4.0-cvs/gcc/configure 
--with-mpfr=/Users/
nburrell/usr --with-gmp=/Users/nburrell/usr --prefix=/Users/nburrell/usr 
--enable-
languages=c,f95

running the command gfortran -Wall -v -save-temps test_gfortran.f90 gives the 
following output:
