http://d.puremagic.com/issues/show_bug.cgi?id=4854 Can somebody please help to track this down further? Does it crash with: import std.stdio; void main() { writeln("abc", 0);} ? Does it crash with: import std.string; void main() { format("%d", 0); } ? Does it crash with: import std.string; void main() { writefln("abc"); } ? If it crashes with writeln, it's probably a compiler code generation bug, related to varargs. And can you get a stack trace? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=4854 Created an attachment (id=823) Patch I'm adding my patch here as well so it doesn't get lost. I've created a patch but I'm not completely sure if it solves the problem or not. 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.

http://d.puremagic.com/issues/show_bug.cgi?id=4854Is anyone still running 10.5? That's two OSX versions ago.I don't know. But I see now reason why we shouldn't support 10.5 as long as it doesn't cause too much problem. We're still supporting Windows XP which is two versions ago as well and is far older than Mac OS X 10.5. And yes, I know you can't really compare Mac OS X and Windows in this case. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
