Created an attachment (id=1177)
Source code for test case

Given the attached code (also available at
https://gist.github.com/5a0b4685c6d316620c86 ) there is a range error when
trying to access a named capture group when using a static regex object.

When removing static from the declaration of the regex object there is no range
error on runtime.

The attached test case is run as follows.

$ dmd -run regex.d
c[1]      = a
c["nick"] = a

$ dmd -version=Static -run regex.d
c[1]      = a
