           Summary: Unmanageable compiler error
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: fmartinez@gmv.com


Created attachment 24732

The file where the error is generated at line 1495

The submitted code generates the following error that I cannot debug with the
provided information.

t_element_pure_vector_ftl.f90: In function ‘ftl_vector_init’:
t_element_pure_vector_ftl.f90:1495:0: error: type mismatch in binary expression
integer(kind=8)

integer(kind=8)

integer(kind=4)

num.25 = num.25 + 1;

t_element_pure_vector_ftl.f90:1495: confused by earlier errors, bailing out


The compiler options are

-g -std=f2003 -fprofile-arcs -ftest-coverage -fbacktrace -fbounds-check
-fno-range-check -fconvert=big-endian -Wall

This code compiles and runs properly with intel 11, 12 and g95

seems to fix it.  I'll try to reduce the testcase and bootstrap/regtest it.
