small program to demonstrate:
COMPLEX AVC
AVC = CLOG( (-10.0, -10.0) )
PRINT*,AVC
END
from g77:
$ g77 y.f
$ ./a.out
(2.64915872,-2.3561945)
from gfortran:
$ gfortran y.f
$ ./a.out
( 2.649159 , 0.7853982 )
$ gfortran --version
GNU Fortran 95 (GCC 3.5-tree-ssa 20040311 (merged 20040307))
This makes it a front-end issue, I think:
MAIN__ ()
{
complex4 avc;
avc = __complex__ (2.649158954620361328125e+0, 7.85398185253143310546875e-1);
_gfortran_filename = "y.f";
_gfortran_line = 3;
_gfortran_ioparm.unit = 6;
_gfortran_ioparm.list_format = 1;
_gfortran_st_write ();
_gfortran_transfer_complex (&avc, 4);
_gfortran_st_write_done ();;
}
