--- Comment #6 from Jens Maurer <jens.maurer at gmx dot net> 2010-10-27 13:15:19 UTC --- Thanks. Yes, the testcase was reduced from preprocessed files. Unfortunately, you can't remove the "#pragma interface" without breaking the testcase. But the only documented effect that "#pragma interface" should have is that I get linker errors, i.e. undefined symbols.
