            Bug ID: 58516
           Summary: ICE with __transaction_atomic
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following code snippet (compiled with "-std=c++0x -fgnu-tm") triggers an
ICE since GCC 4.7.0 (when transactional memory was introduced):

=================================================
void foo()
{
  __transaction_atomic noexcept(false) {}
}
=================================================

bug.cc: In function 'void foo()':
bug.cc:3:41: internal compiler error: tree check: expected class 'expression',
have 'exceptional' (statement_list) in finish_transaction_stmt, at
cp/semantics.c:5202
