ModuleDefinition.ReadModule hangs permanently

[Metalnem]

ModuleDefinition.ReadModule hangs permanently when attempting to read the module from the attached archive. You can run the following code to reproduce it (the path variable should contain the path to the extracted file):

ModuleDefinition.ReadModule(path, new ReaderParameters(ReadingMode.Immediate));

Found via SharpFuzz.

Nice find! This occurs because an entry in the assembly metadata TypeRef table of Test.dll is self-referencing. Specifically, entry 11 - DebuggingModes has a ResolutionScope of 0x2F (itself).

Cecil does not do any handling of recursive references and will enter an infinite loop while following the references.

Thanks for reporting this.
