           Version: tree-ssa
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org

 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-cygwin

This ICE was discovered while building a cygwin cross compiler, however, the
compiler crashes in the same place on the preprocessed source with a native
Linux x86 toolchain.  I'll upload the preprocessed source.
