Bug 18916 – ICE using Typedef and __LINE__

This code: import std.typecons: Typedef; alias Line = Typedef!int; void foo(Line line = __LINE__) { } void main(){ foo(); } On DMD: __LINE__ Illegal instruction (core dumped) On LDC2: Error: Internal compiler error: Type Expression not implemented: __LINE__

Attempted Fix: https://github.com/dlang/dmd/pull/8310

Alternate test case that doesn't require Phobos. struct Line { int line; alias line this; this(int line) { this.line = line; } } void foo(Line line1 = __LINE__, int line2 = __LINE__, int line3 = int(__LINE__)) { assert(line1 == 12); assert(line2 == 21); assert(line3 == 12); } void main() { foo(); }

Same issue, but for __FILE__ --- module1.d module module1; struct File { string file; alias file this; this(string line) { this.file = file; } } void foo(File file1 = __FILE__, string file2 = __FILE__) { assert(file1 == "module1.d"); assert(file2 == "main.d"); } --- main.d import module1; void main() { foo(); }
