[Bug fortran/20063] New: gfortran assembler error - : Bad Absolute Expression, absolute 0 assumed.

[dir at lanl dot gov]

I get this error with the Macintosh gfortran from the 20050213 package with some
of my programs.

Your code compiles fine on amd64-*-freebsd where I'm using a gfortran
form 20050218 sources.  I do get a warning though

troutmask:kargl[205] /usr/tmp/sgk/bin/gfc -c e.f
/var/tmp/ccvV0Vua.s: Assembler messages:
/var/tmp/ccvV0Vua.s:39: Warning: .space repeat count is zero, ignored
/var/tmp/ccvV0Vua.s:99: Warning: .space repeat count is zero, ignored

I suspect that this a target specific bug or it could be related to
a serious bug introduced on 2/13 and fix last night.

Darwin's as treats those warnings as errors as they really should as this is a bug
in the front-end.
If you take a look at my reduced testcase and look at the assembly ouput you will see that
the assembly outputed is wrong.

i.e. the elements that are filled in with a repeat count are not padded to the
correct length.

Well, more precisely: they're zero-padded instead of being padded with blanks.

This will likely change to an ICE in varasm.c after my CONSTRUCTOR patch goes 
in.
