--- Comment #6 from Jack Howarth <howarth at nitro dot med.uc.edu> 2011-03-19 22:02:58 UTC --- Doesn't the darwin linker developer's comments on PR48097 (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48097#c8) imply that libjava's Throw2 test case is expected to fail on the current Apple system unwinder? Thus your epilogue patch should be fine as it only regressed Throw2 for me.
