------- Comment #1 from burnus at gcc dot gnu dot org 2007-11-20 11:34 -------
The problem is that you end up in the wrong file. If you enter "break 3" you
are debugging the wrapping program not the Fortran "program test", which is the
reason that there is no "i" available.
Try: break file.f:line, e.g.
(gdb) b b.f:2
However, there is another problem: One cannot set the break point after the
assignment:
program test ! Breakpoint possible
i = 1 ! Breakpoint possible
! Breakpoint here ! No breakpoint possible
end ! No breakpoint possible
Setting a breakpoint in line 2, one can print the value "i" before the
assignment; however, doing a "step" one ends in the wrapping main() program and
can thus never read the value after the assignment.
Using g77 or ifort, one can set a break point in line 3 or 4 and gdb shows
then:
Breakpoint 1, test () at b.f:4
4 end
