Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit X-IsSubscribed: yes X-SW-Source: 2015-07/txt/msg00153.txt.bz2 Hi all, I filed this bug recently: https://sourceware.org/bugzilla/show_bug.cgi?id=18600 In short, gdb sometimes leaves stopped newly spawned threads created by a fork child. The "sometimes" happens quite often, so it's very easy to reproduce. This has the effect of leaving (part) of your program stopped while you expect it to be running. "info threads" shows the threads as running while in reality they aren't. Is this bug serious enough to be on the blocking list for 7.10? I would think so, as it's a regression compared to 7.9. However, I don't want to impose work on anybody (e.g. Pedro, or anybody else familiar with the linux-nat subsystem), which is why I am asking. I am willing to put time on this, but the chances of me successfully fixing the bug are quite slim. Thanks! Simon
