Is betterC affect to compile time?

[Oleg B]

Hello everyone!

I try build this code with betterC

import core.stdc.stdio;
import std.format : format;

extern(C) int main()
{
     mixin(format!`enum str = "%s\0";`("hello"));
     fprintf(stderr, "%s\n", str.ptr);
     return 0;
}

but compilation fails

/dlang/dmd/linux/bin64/../../src/phobos/std/format.d(6278): 
Error: Cannot use try-catch statements with -betterC
/dlang/dmd/linux/bin64/../../src/phobos/std/format.d(6308):

str = \"%s\\0\";", string)` error instantiating

  while evaluating: static assert(!e)
/dlang/dmd/linux/bin64/../../src/phobos/std/array.d(3204): Error:

Is this a bug?
