SegFaults when using Fibers

[Danny Arends]

(Also posted this in bugs, but I think it needs to be here)

When I try to print floats and doubles from a fiber it fails with a
segfault, while it is possible to do the same in the main thread.

The expected output of the attached code file:
15
15
Done

However I get:
15
segfault

I am using the DMD64 D Compiler v 2.054 on Debian 64

What am I doing wrong, because using to!string() on the floats and
double allows me to print them to std.out.

I however get weird behavior when I try to do math on the floats and
doubles in the fiber, or when I pass them to C-functions.

Any Help would be appreciated
Kind regards,
Danny
