--- Comment #6 from Iain Sandoe <iains at gcc dot gnu.org> --- a quick look at current results for other platform versions suggests that: * x86_64-darwin10 [64b runtimes, but 32b kernel] is also affected but * from darwin11+ [64 kernel] the main fail is FAIL: cxa4001 which is a known issue. my darwin10 box is v. slow (and I lost a bunch of runs on Weds from a power outage) but will post the 889 results for Darwin10 when it's done.
