--- Comment #8 from Richard PALO <richard at netbsd dot org> --- (In reply to Richard PALO from comment #7) > Further testing indicates that 'cdecl' is okay and that keeping 'regparm(0)' > causes the error. Is there perhaps a hint where I could checkout in the code, or is this a case of a faulty program (in this case xulrunner)... since this test code compiles without errors/warnings with clang++ 3.5, it would seem that it should be okay.
