             Bug #: 54552
           Summary: Cast to pointer to VLA crash the compiler
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: jens.gust...@loria.fr

code to reproduce the problem

I stumbled int to a case where a cast (double(*)[n]) crashes the compiler,
whereas first having a typedef for the VLA works ok.

I attach code that reproduces the problem for me. The bug is present as well in
gcc 4.6.3 as in 4.7.0. This is on an ubuntu x86_64, but I don't think that this
should matter.
