Regex problem

[James Blewitt]

I am having a problem with regexes.
The following code causes a compilation error, whereas if I 
comment out the regex outside of main and comment in the regex 
inside main, it does compile.

I'm using DMD v2.058.

<code>
import std.regex;

Regex!(char) testRegex = regex("\\b(A(Z)?|B(Z)?|C(Z)?)\\b", "i");

void main() {
//	Regex!(char) testRegex = regex("\\b(A(Z)?|B(Z)?|C(Z)?)\\b", 
"i");
}
</code>

The error is:

<code>
