Bug 15922 – DMD segfault in functionParameters()

Dmd segfaults when compiling this code: template StorageAttributes(Store) { enum hasInsertMethod = Store.insert; enum hasFullSlice = Store.init[]; } struct ValidSparseDataStore(DataT) { DataT insert() { correctedInsert!(false); } DataT correctedInsert(bool CorrectParents)() {} auto opSlice() inout {} } alias BasicCubeT = StorageAttributes!(ValidSparseDataStore!int);

Currently, `FuncDeclaration.semantic3` fails if the parent has error, so the body of aggregates that already have errors is not processed. However, the code was only `return`ing and not setting `Dsymbol.errors` to `true`, resulting in this error being unnoticed by `functionSemantic`. https://github.com/D-Programming-Language/dmd/commit/bd46f551bb30999c68d3c79c284d6ac2af123d9b Merge pull request #5659 from mathias-lang-sociomantic/fix15922 Fix issue 15922: DMD segfault in functionParameters on invalid code
