[Bug fortran/22021] New: gfortran dies with Bus error

["Russell dot Edwards at csiro dot au" <gcc-bugzilla at gcc dot gnu dot org>]

Trying to compile the attached ancient fortran source file, gfortran dies with a bus error. g77 doesn't 
have a problem with it.

parpos.f: In function 'parpos':
parpos.f:100: internal compiler error: Bus error


The system is Mac OS X 10.3.9 with gcc 4.1.0 . 

A minimal test file with just the offending line and minimal declarations etc does not reproduce the 
bug.
