          Issue ID: 23350
           Summary: Nondeterministic test failure in std.concurrency
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody puremagic.com
          Reporter: snarwin+bugzilla gmail.com

std.concurrency's test suite will sometimes fail due to a segfault in a static
module destructor. [1]

So far, this failure has been observed on 64-bit Linux, and resulted in the
following stack trace (demangled):
