Ticket #246 (closed defect: fixed)

function definition is broken for tuple arguments

Reported by: ChristianK Assigned to: lindquist

Description

The test case (run/t/tuple_15_A.d): 

template TypeTuple(TList...){
	alias TList TypeTuple;
}

void main(){
	auto y = function(TypeTuple!(uint,uint) ab){};
}

triggers the assert in functions.cpp:723 

f->fty.args.size() == fd->parameters->dim

with 2 == 1. This is because TypeFunction has tuples unfolded whereas 'ab' is only a single VarDeclaration in fd->parameters.

This fails on DMD too.

FuncDeclaration::semantic3() tries to expand parameter tuples, but seems to fail in this case; apparently the type is still a template instance, not an actual tuple, when it runs.

  • status changed from new to closed.
  • resolution set to fixed.

Should be fixed in r1177. Maybe this should also be submitted to Walter?

This was D bug #854. I've attached a patch there.
