Can't do much about the bug in 2.16.1. 2.16.1 incorrectly handles the fixup associated with the difference of two symbols. The two 32-bit portions of a 64-bit difference are swapped in 2.16.1. This affects dwarf debugging output and EH exception support. I recently made dwarf2 EH support the default on both the 32 and 64-bit hpux ports to use EH exception support. I would have liked more time between the gas fix and enabling this feature, but Richard was pushing. I believe that you can avoid these errors by using the sjlj exception support. In a sense, these errors aren't regressions as the dwarf2 eh support is new. With cvs binutils, I don't see any regressions relative to the previous sjlj support on this target.
