Please clarify, in ptrace_notify code path, is it allowed that ptraced thread can ignore signals (such as SIGTRAP) without telling debugger what happened? This is key problem I'm not quite sure... Because if the test doesn't block SIGTRAP, it works on IA64 too.. Hope I have made the problem clear... -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
