            Bug ID: 60869
           Summary: ICE on throw after invalid definition of __cxa_throw
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: harald at gigawatt dot nl

typedef void __cxa_throw(void *, void *,  void (*) (void *));
void f() { throw 1; }

gives

unhandled expression in get_expr_operands():

Sort of expected, this ICEs on every version of GCC I can test right now
(release versions of 4.1.2 to 4.8.2, and 4.9 as of about a month ago)
