problem with formattedWrite to OutputStream

[ghost]

Using DMD64 D Compiler v2.068.0:

/usr/include/dmd/phobos/std/range/primitives.d(335,9): Error: static assert  "Cannot put a const(char) into a OutputStream."

dmd failed with exit code 1.

Same error with fresh clone of master.

Hmm, same issue with gdc 4.9.2 (based on 2.066?):
