Comment (by howarth.at.macports@…):

 This is due to the recompilation of libunwind in 10.11 using Apple Clang 7
 producing new valid optimizations (according to Apple) that tickle an
 unknown bug in FSF boehm-gc.

 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66848

 Don't expect any fixes from Apple as they can't touch the GPLv3 code to
 look at the FSF boehm-gc problem (unless they used the gcc43 package which
 should still be GPLv2).
