Reduced:

inout(char)[] foo(inout(char)[] text) {
     import std.regex;
     static auto inlineRE = ctRegex!`\$\(ta (.*?)\)`;
     return text.replaceAll!(m => textAttr(m[1]))(inlineRE);
}

void main() {
}

This may be an oversight in the regex module that it may not be 
well-tested with inout data. If others agree, please open a bug report.

Meanwhile, can you try the following template which works at least for 
the reduced code:

import std.range;

auto foo(S)(S text)
         if (isSomeString!S) {
     import std.regex;
     static auto inlineRE = ctRegex!`\$\(ta (.*?)\)`;
     return text.replaceAll!(m => textAttr(m[1]))(inlineRE);
}

void main() {
}
