For a given class, this method may be run multiple times in order to resolve forward references. The method incrementally tries to resolve the types referred to by the members of the class. The subsequent calls to this method are short-circuited if the class members have been fully analyzed. For this the code tests that it is not the first/main call to the method (semanticRun == PASS.init else branch), scx is not set, and that the cldec.symtab is already set. If all these conditions are met, the method returns. But before returning, the method was setting cldec.semanticRun to PASS.semanticdone. It should not set semanticRun since the class has not been fully analyzed yet. The base class analysis for this class could be pending and as a result vtable may not have been fully created. This fake setting of semanticRun results in the semantic analyzer to believe that the class has been fully analyzed. As exposed by the issues 19656, 19657, 19746 and 19750, it may result in compile time errors when a derived type class is getting analyzed and because of this fake semanticdone on the base class, the semantic analysis construes that an overridden method is not defined in the base class. Issue 19655 exposes a scenario where a buggy vtable may be created and a call to class method may result in execution of some adhoc code. https://github.com/dlang/dmd/pull/9471 -- |
