Regex question

[James Blewitt]

I'm having a problem with regexes.
The following code gives a compilation error.  If I comment out 
the regex outside of main and comment in the regex inside of main 
then it does compile.

I'm using DMD v2.058

Any ideas what is going on?

------

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");
}
