           Summary: Regression in g++.dg/parse/stack1.C
           Product: gcc
           Version: tree-ssa
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code, xfail
          Severity: normal
          Priority: P2
         Component: middle-end
        AssignedTo: unassigned at gcc dot gnu dot org

This test case has 11,000 chained else if's.  We fail because gimplify_cond_expr
isn't written to allow tail-calling, and exhaust stack space.  There's enough
complexity in that function that the transformation would be non-trivial.

The test will be xfailed on the branch, but must be fixed before merging.
