Bug 15835 – Segfault with typeid call from lazy argument

This program segfaults using both DMD 2.070 and latest Git master (2d1f4f6): --- extern(C) int printf(const char*, ...); class A {} void fun2() { auto symbol = new A; fun3(fun4(typeid(symbol))); } string fun4(ClassInfo t) { return t.name; } void fun3(lazy const(char)[] c) { printf("%.*s\n", c.length, c.ptr); } void main() { fun2(); } --- The issue seems to be that `symbol` is not added to the list of closure variables in fun2, i.e. is not part of the nested context as expected during codegen for the implicit lazy delegate. Reported by Timothee Cour as LDC issue #1369 (https://github.com/ldc-developers/ldc/issues/1369).
