Bug 10016 – Incorrect error gagging using RefCounted

struct RefCounted(T) { struct RefCountedStore { struct Impl { T _payload; } Impl* _store; } RefCountedStore _refCounted; void opAssign(typeof(this)) { } void opAssign(T) { } @property refCountedPayload() { return _refCounted._store._payload; } alias refCountedPayload this; } struct S { int i = malloc; } class C { } class N { this(C) { } C c() { return null; } } class D : N { this() { super(c); } RefCounted!S _s; } 2.063: ----- Fatal Error: Out of memory ----- 2.062: ----- main.d(22): Error: undefined identifier malloc main.d(42): Error: template instance main.RefCounted!(S) error instantiating ----- DustMite did a good job :]

You can replace malloc with someRandomUnknownIdentifier.

https://github.com/D-Programming-Language/dmd/pull/1983 With git head(75d3660), "Out of memory" error does not occur. Instead, the OP code reports no error with -o- switch (different from 2.062), and cause "Internal error: backend\dt.c 106" with -c switch. AFAICS this is a front-end issue. the code should report "undefined identifier" error as same as 2.062, but the error is incorrectly gagged.

Compiler fix is now merged, and incorrect error gagging issue is fixed. But, I cannot still confirm that the original "Out of memory" error. Henning, could you please check your code with git head. If the original issue is really fixed, close this issue.

It works now, good job. Reverting your commit leads to Out Of Memory again. But why do you get an ICE? I'm on Linux x64.
