digitalmars.D - Bus error w/combined writeln(int) and uniform

reply Magnus Lie Hetland <mlh idi.ntnu.no> writes:
Tried to see if I could find this in the issue tracker; sorry if I  
missed it. (Maybe it manifests with something other than a bus error  
on other platforms?)

Anyway, when I run the following program in OS X (using dmd 2.051), it  
first prints out 1, and then I get a bus error:

import std.random, std.stdio;
void main() {
     writeln(1);
     auto y = uniform(0.0, 1.0);
}

Writing a string instead, for example, removes the problem (as does  
many other minor changes; I've tried to eliminate as much as possible  
from my original program while retaining the bug).

Is this already known, or should I submit it?

Thanks,

- M

It works fine on Linux, which means the bug is likely OSX specific.  I 
only know of one "mysterious OSX segfault" bug currently in Bugzilla, but 
I'm not sure if it's related:

Thanks for the tip. I have no idea if they're related either; it seems 
I did get a segfault (and bus error) under other circumstances as well. 
I guess maybe I'll add a comment to the bug.

To begin with, are you using Mac OS X 10.5 or 10.6? If you're using 10.6 
we can rule out that bug.

I'm using 10.5.8.

That's the same one, no? (Did mean some other problem?-)

No I meant the same, sorry for the additional post and confusion.
