          Issue ID: 24530
           Summary: Rethrowing exception outside of catch clause segfaults
                    with -dip1008
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: chloekek@use.startmail.com

Steps to reproduce:

-----
$ cat example.d
import std.stdio : writeln;
void main()
{
    Throwable a;
    try
        throw new Exception("A");
    catch (Throwable b)
        a = b;
    writeln(a);
}
$ dmd example.d
$ ./example
object.Exception@example.d(6): A
----------------
??:? _Dmain [0x44f8e8]
$ dmd -dip1008 example.d
$ ./example
zsh: segmentation fault (core dumped)  ./example
-----

s/writeln(a)/throw a;/ likewise segfaults. I suspect that a is dangling.
