           Summary: Custom unittest runner on phobos fails due to segfault
                    on fork() exiting
           Product: D
           Version: D2
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos

This
(https://github.com/dlang/phobos/blob/6bd92f053f564e3f20db137d11a2679320d9702e/std/stdio.d#L1659)
`exit(0)` call from libc does an exit sequence before exit and therefore
doesn't exit immediately. This causes some unittest runners on phobos to fail
due to segfault on the exit sequence.
