           Summary: Bug in ctRegex - "Error: found 'else' instead of
                    statement"
           Product: D
           Version: D2
          Hardware: Other

The following regular expression string (valid as it works in non-compile time
regex) causes the "Error: found 'else' instead of statement" compile time
message:

"/usr/include/dmd/phobos/std/regex.d-mixin-5885(5943): Error: found 'else'
instead of statement"

import std.regex;

auto commentRx = ctRegex!(`.*?(//.*[\r\n]|/\*(?:.|[\r\n])*?\*/)`, "gm");

void main() {}
