This error is showing up with several programs and it changes if I reduce the
program very much - I will add the second error that shows up as a seperate report-

I am thinking this is a fortran front-end bug:
reduced testcase:
COMMON /SUBSTR/ NPHASE,NSUB
END
SUBROUTINE ZIPP
COMMON /SUBSTR/ NPHASE,NSUB,IDUM1,KURPA,KTBUF
IF (NSUB.LT.0) THEN
KTBUF=KTBUF-1
END IF
END
I think we get the wrong type for the common section, SUBSTR.

Another reduced testcase:

Definitely an FE oddity. The operand scanner is told to get the operands of a
COMPONENT_REF that's accessing a non-existant field:
(gdb) ptu stmt
substr.ktbuf = D.485;
(gdb) ptu expr
substr.ktbuf;
(gdb) call debug_variable(ref)
substr, UID 475, struct
{
int4 nphase;
int4 nsub;
}, is global, call clobbered, sub-vars: { SFT.25 }
(gdb)
There is no field named 'ktbuf'. This is confusing all the sub-var machinery,
leading to this ICE.
Paul, could you take a look?
