| if (c + 1 == nullptr || (!isalnum(c[ 1]) && c[ 1] !='_')) continue; |
should this be maybe guarded?

I'm assuming here that c is not nullptr, because typesDesc is expected to be a non-nullptr input. Then, also the c + 1 expression can also never be nullptr. About accessing the elements: reading c[1] is safe because the loop condition *c guarantees c[0] != '\0', so c[1] is at most the null terminator.
A class name in a selection XML can span multiple lines. `CleanType()` only treated `' '` as a blank, so a newline was kept in the cleaned name and, when the template arguments were later re-processed individually, an argument starting with a newline was truncated to an empty string. This corrupted the rootmap entries and the alternate name registrations (e.g. `"Foo<,vector<float>,>"`), leading to `"Second registration of ..."` errors from `TClassTable::AddAlternate` at library load time. Treat all whitespace like a space: drop it where a space would be dropped, and emit a single plain space where it separates two identifiers. Closes root-project#22359. 🤖 Done with the help of AI.
