           Summary: Regression in g++.dg/ext/stmtexpr1.C
           Product: gcc
           Version: tree-ssa
            Status: UNCONFIRMED
          Severity: normal
          Priority: P1
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rth at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org

In this test case, gimplification attempts to create a temporary of class A.
Since A has a constructor, this triggers an abort.  We need to either refactor
the TARGET_EXPR handling in gimplify.c or rearrange how the front end presents
this information.

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