            Bug ID: 18600
           Summary: After forking and threads spawning, gdb leaves newly
                    created threads stopped
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: threads
          Assignee: unassigned at sourceware dot org
          Reporter: simon.marchi at ericsson dot com
  Target Milestone: ---

When a program forks and the fork childs start threads, some newly created
threads are left stopped by gdb. It's easy to reproduce with the following
example:

https://github.com/simark/gdb-fork-threads-test/

It worked with gdb 7.9, I bisected it and found that this commit introduces the
regression.
