[Bug fortran/30410] New: Host association bug w/ EXTERNAL

[anlauf at gmx dot de]

The attached code demostrates a host association bug
with a declaration of an external function in a module.
The incorrect reference can be verified by looking at
the assembler or object files generated.

% gfc gfcbug53.f90
/tmp/ccDZrLiD.o(.text+0x37): In function `__mod2__foo':
: undefined reference to `__mod2__extfunc'
% gfc gfcbug53.f90 -c && nm gfcbug53.o |grep extfunc
         U __mod2__extfunc
00000047 T extfunc_

See the lines
  real, external :: extfunc     ! This EXTERNAL refers to the wrong namespace
                                ! Check with: nm gfcbug53.o |grep extfunc
and the attached code for details.

Cheers,
-ha
