Bug 1408 – Assertion failure: 'd' on line 4234 in file 'mtype.c' on faulty d code

The compiler crashes when i try to compile the following faulty d code: ------- struct ABC() { alias NonExistentTemplate!() y; } void main() { auto abc = new ABC!(); foreach (x; abc.y) {} // Required for the compiler to crash } ------- The output of the compiler is: ------- ass4234.d(3): template instance identifier 'NonExistentTemplate' is not defined ass4234.d(8): template instance ass4234.ABC!() error instantiating Assertion failure: 'd' on line 4234 in file 'mtype.c' abnormal program termination ------- It does, however, not crash if you don't use a template in the template ABC or if you comment out the foreach loop. This bug is uncritical for development because the compiler actually shows all the errors before crashing...

The following code also crashes with the same "Assertion failure" message. ---- struct X { import std.stdio; } void main() { X.std.stdio.writefln(""); } ---- However the following code compiles and runs ... ---- struct X { import std.stdio; } void main() { X.writefln(""); } ----

Can we close this one? It looks like a dupe of #1783 and that was closed by 1.026

(In reply to comment #1) > The following code also crashes with the same "Assertion failure" message. > ---- > struct X > { > import std.stdio; > } > void main() > { > X.std.stdio.writefln(""); > } The error message now gives is slightly different to this title. Closing this bug and re-opened as BUG 2489.
