           Summary: compiler segfault on single default constructor
                    argument
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd

          Reporter: lr@decard.io

I Found that when i use the buildPath() as the only default argument in a class constructor it causes a segment fault in the compiler.

---
import std.path;

class A {
    this(string path = buildPath("a", "b")) {
    }
}

void main() {
    auto a = new A();
}
