[Bug fortran/20059] New: internal compiler error: Segmentation Fault - For common blocks

I get an Segmentation Fault with the Macintosh gfortran from the 20050213
package for this program.

Confirmed, but note I think this is the same as PR 19387 even though there is no ICE in that bug.

Does this still segfault on powerpc? On i686 I get:
 In file pr20059.f90:10

This is most likely because building a compiler for i686, HWI is 32bits but for PPC, it is 64bit and 
because of PR 19387, we don't deal with HWI in the fortran front-end error/warning functions don't 
understand HWI.  (HWI == Host_Wide_int).

Can you try this patch, Andrew?  The required padding should never overflow 2^32.

Sorry for not replying sooner, exams got in the way.  But yes this fixes the problem.
