           Summary: ICE in code involving procedure pointers
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: townsend@astro.wisc.edu

Source code for ICE-causing module

The attached module source code causes an Internal Compiler Error during
compilation (gfortran -c gfortran_ice.f90). I'm guessing this might have
something to do with the use of procedure pointers.

This is on OS X 10.6.7 with gfortran 4.6.1 (20110325) built within macports.

Your code compiles on x86_64-*-freebsd with 4.6.1 20110509
and gcc version 4.7.0 20110509.  There have only been a 
handful of patches to the 4.6 branch since 20110325, but
it isn't clear if these should help.  valgrind on the 4.6.1
f951 does not show anything bad.  This could be target
specific.  Can you get a backtrace with a debuggers?

I can reproduce the failure with 4.6.1 20110421 (rev. 172818) and with
openSUSE's 4.6.0 20110427 (Rev. 173021). However, it works with 4.7.

Valgrind shows:

==10880== Invalid read of size 4
==10880==    at 0x5A3453: gfc_get_nodesc_array_type (trans-types.c:1433)
==10880==    by 0x5A59D7: gfc_sym_type (trans-types.c:1977)
==10880==    by 0x5A5164: gfc_get_function_type (trans-types.c:2575)
==10880==    by 0x5A5B2A: gfc_get_ppc_type (trans-types.c:2136)
==10880==    by 0x5A4CFF: gfc_get_derived_type (trans-types.c:2289)
==10880==    by 0x5A5048: gfc_typenode_for_spec (trans-types.c:1060)


(I think it could be a duplicate of PR 48588 (fixed Apr 19 for 4.7 and Apr 26
for 4.6). Or not - the program also fails with -fno-whole-file whereas PR
48588's example works with that option.)

Works for me with revisions 4.6.4, 4.7.3, 4.8.1, and trunk. Closing as fixed.
