I downloaded the Foyer Consulting rpm distribution of the pgcc and pgcc-g77
fir the i686 processors last weekend.  I tried compiling one of my production
programs that compiled ok with the version of g77 that came with Redhat 
Linux package 5.1.  The compile failed with an internal compiler error. 
I was able to isolate the problem to a small routine.  The needed data
follows since it is rather short:



The script file contents used to invoke g77:

#!/bin/sh
/opt/pgcc/bin/g77 -fversion -fno-globals -fno-silent 2>outp -v -O0  check2.f


The contents of check2.f:
C

C
C
      SUBROUTINE TO_UPPER(
     M            STRING)
C
C     Convert a character string from lower case to upper case

      CHARACTER*(*) STRING

C     + + + ARGUMENT DEFINITIONS + + +

C     + + + LOCAL VARIABLES + + +

      INTRINSIC  ICHAR, LEN, CHAR
C***********************************************************************
      IEND = LEN(STRING)
      DO 10 I = 1, IEND
        ICH = ICHAR(STRING(I:I))
        IF(ICH.GE.97 .AND. ICH.LE.122) THEN
C         Character is lower case.
          STRING(I:I)= CHAR(ICH-32)
        ENDIF
 10   CONTINUE

      RETURN
      END


The contents of outp after the failure of the compiler:

I hope this can be used to sniff out the problem.  Meanwhile I will seek 
an alternative to this routine and see if I can get my program to compile.

                                            Thanks
