Re: Darwin -m64 results


FX,
   That was spot on. If I reduce the test case down to...

! { dg-do run }
! Program to test ASSIGNing a label to common variable. PR18827.
      program test
      integer i
      common i
      end

I still get the linkage error...

gfortran -O3 -g -m64 assign.f90
can't find atom for N_GSYM stabs i:G(0,3) in /var/tmp//cct3ktdf.o

This happens with the -g flag and -m64 at all optimization levels.
The problem doesn't occur if I don't link the program. The .s for
the above file shows...

Geoff, I assume the linker is choking on the line...

        .stabs  "i:G(0,3)",32,0,4,0

...right?
