--- Comment #1 from Richard Henderson <rth at gcc dot gnu.org> 2011-03-12 22:03:29 UTC --- It is not TM related. If you remove the TM constructs, the test case still crashes with stack overflow in mainline. Of course, there are a number of errors produced beforehand, which puts this as an ice-on-illegal test, which would be lower priority. Can you reduce this test case again without the errors?
