Description Brian White 2008-03-30 16:43:40 UTC 
Creating and destructing an instance of Thread will cause a SEGV if nothing is done in between.

--------------------
import std.thread;
void main(char[][] argv)
{
    scope Thread t = new Thread();
    printf("never mind...\n");
}
--------------------

dragon:~/tmp> dmd dtest.d
dragon:~/tmp> ./dtest
never mind...

Fix SEGV in std.thread

This bug is present in the D1 Phobos library too. The fix is trivial in both cases, and attaching a patch.

Comment 2 Lars T. Kyllingstad 2010-08-13 04:14:15 UTC 
This is now D1 only.  D2 doesn't have std.thread anymore, and the problem doesn't seem to exist in core.thread.

Also:  There is no ICE (Internal Compiler Error) here, so I'm removing the ice-on-valid-code keyword.
Comment 3 Andrei Alexandrescu 2015-11-03 19:11:53 UTC 
It's unlikely this D1 issue will get worked on. If it applies to D2 as well and/or if anyone plans to work on it, please reopen.
