           Summary: ICE with -fdump-tree-all-all in vector indexed access
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org

Code example to reproduce ICE

GCC tries to access varmap through get_varinfo in tree-ssa-structalias.c, but
it fails with an ICE.

I have attached a reduced code example to reproduce the problem.

The command line and output with 4.8.1 is:
$ ~/work/tmp/gcc-4.8.1/gcc/cc1 -fpreprocessed -fdump-tree-all-all -O2
core_list_join.i 
core_list_join.i:4:1: warning: no semicolon at end of struct or union [enabled
by default]
 }
