Description Alexander Täschner 2005-05-22 09:09:38 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)

Description of problem:
When trying to compile the fortran file below gfortran produces
an internal compiler error.

Version-Release number of selected component (if applicable):
gcc4-gfortran-4.0.0-0.41.fc3

How reproducible:
Always

Steps to Reproduce:
gfortran -c hwbran.f

--- start of file hwbran.f ---
      SUBROUTINE HWBRAN(KPAR)

        IF (NTRY.GT.NBTRY) CALL HWWARN('HWBRAN',100,*999)
        IF (ID.EQ.13) THEN
          IF (QLST.GT.QCDL3) THEN
            QKTHR=2.*HWBVMC(N)
            IF (QLST.GT.QKTHR) THEN
              RN=HWRGEN(N)
            ENDIF
          ENDIF
        ENDIF

  999 END
--- end of file hwbran.f ---

Actual Results:  hwbran.f: In function 'hwbran':
hwbran.f:6: internal compiler error: in convert_move, at expr.c:339


Expected Results:  It compiles without problem with g77.

Comment 1 Jakub Jelinek 2005-05-22 14:05:16 UTC
Simplified testcase:
        SUBROUTINE FOO (A)
        REAL T, A, BAZ
        CALL BAR (*10)
        T = 2 * BAZ ()
        IF (T.GT.0) T = BAZ ()
10      END


Comment 3 Jakub Jelinek 2005-06-06 09:24:19 UTC
Should be fixed in gcc-4.0.0-9 in rawhide.
