------- Comment #1 from matz at gcc dot gnu dot org 2007-05-23 09:36 ------- The ObjC frontend seems to use IDENTIFIER_POINTER directly to produce this encoding. This doesn't contain template arguments anymore. And from quick reading of obj-act.c it's also not clear if it was really expecting funny characters like '<' in those identifiers. It happily uses these names to construct other identifiers. This works fine in C, but in C++, when they still contained template args the new identifiers would contain "<" and ",", surely not something you expect from normal identifiers.
I would suggest auditing objc-act.c carefully, if using IDENTIFIER_POINTER is really correct everywhere. Additionally, someone knowledgable in Obj-C++ should define once and for all what the encoding of such types should be. If it is supposed to include template args, then you need to use a different mean than accessing IDENTIFIER_POINTER. One way would be decl_as_string (t, TFF_DECL_SPECIFIERS | TFF_UNQUALIFIED_NAME); (Or leaving out TFF_UNQUALIFIED_NAME if you also need toplevel namespaces in there). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32052
