However, I think that this set of tests indicates that the bug is that we "emit eh_frames that are incompatible with the darwin {8,9}-unwinder,10-compacter". Accordingly, I suggest that either we close this bug and refer to PR41991 - or we re-name this one to reflect its underlying cause and make it a target bug; Mike - any preference? > - all the dylibs and executable around carry a dependency towards > /usr/lib/libgcc_s.1.dylib hopefully, I have explained both that this is an intention of the current design and why that design must be as it is. If you can think of a viable alternative, I'd be very glad to read it. ... remembering that there are some system libraries and frameworks that are closed source and therefore cannot be re-compiled by an end User - to say nothing of any 3rd party commercial applications the User has installed that were linked against a 'standard' system.
