Bug 4364 – ICE(class.c) compiling a struct def named 'Object' followed by a class definition

This source file crashes the compiler for me: -------------------------- struct Object{} class Game {} -------------------------- ..using dmd2 / windows / VisualD / VS2010Int Changing 'Object' to any other string makes the crash go away. Removing the second line ("class Game {}") makes the crash go away. The assert is: Assertion failure: 'b->type->ty == Tclass' on line 449 in file 'class.c' In 'class.c' in the src directory (C:\dmd\src), the assert appears to be on line 446. Function: void ClassDeclaration::semantic(Scope *sc) Code: // If no base class, and this is not an Object, use Object as base class if (!baseClass && ident != Id::Object) { // BUG: what if Object is redefined in an inner scope? Type *tbase = new TypeIdentifier(0, Id::Object); BaseClass *b; TypeClass *tc; Type *bt; if (!object) { error("missing or corrupt object.d"); fatal(); } bt = tbase->semantic(loc, sc)->toBasetype(); b = new BaseClass(bt, PROTpublic); baseclasses.shift(b); assert(b->type->ty == Tclass); **** LINE 446 **** tc = (TypeClass *)(b->type); baseClass = tc->sym; assert(!baseClass->isInterfaceDeclaration()); b->base = baseClass; }

Root cause (no patch yet): The special cases for class names need to be moved from the class constructor, into the aggregate constructor.
