CTFE using of replaceAll from std.regex posible?

[Martin Tschierschke via Digitalmars-d-learn]

Hello,
when trying to process an string at compile time with
  ...
  auto reg = ctRegex!`as\ [a-z]+`;
  enum replaced = replaceAll(call,reg,"");

I get:
/usr/include/dmd/phobos/std/regex/package.d(708,34): Error: 
malloc cannot be interpreted at compile time, because it has no 
available source code
/usr/include/dmd/phobos/std/regex/package.d(708,27):

0u, 0u, null), null);) , __slRegex3165).this(input, re)

src/app.d(13,29):        called from here: replaceAll(call, reg,

It there a way to use "replaceAll" at compile time?
