Gang, I don't know exactly what the gdb(1) problems on Alpha are, but we do have a problem that's probably not specific to an architecture. The problem is basicly this: one cannot debug any programs because gdb(1) gets a SIGTRAP delivered when it invokes ptrace(2) and never gets a change to wait4(2) the "interior" process. I don't know the details, but one of the following can be the case 1. We now deliver a SIGTRAP, when we didn't do so before, 2. The SIGTRAP comes too quick, it should be "caught" by the wait4(2). I couldn't find any indication that 1 happened, so my guess is that we suffer from 2. Is this known? Any thoughts? -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
