[phobos] Showstopper bug: Hello world fails on OSX!

[Jacob Carlborg]

I've created a patch but it doesn't solve the problem: http://tango.pastebin.com/Pn2tVjSm . I don't get an error in __tls_get_addr now but instead I get this:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000
0x97655133 in strncmp ()
(gdb) bt
#0  0x97655133 in strncmp ()
#1  0x0000101c in ?? ()
Previous frame inner to this frame (gdb could not unwind past this frame)
(gdb)

Maybe someone else can look at the patch and see if I did something wrong or maybe the solution we thought of couldn't fix the problem.

Or if you don't want to look at Tango source files at all you can look at this druntime change: http://www.dsource.org/projects/druntime/changeset/372 , to be more specific: http://www.dsource.org/projects/druntime/browser/trunk/src/rt/image.d?rev=372#L105
