Comment(by dports@…):

 There's also some discussion of this in #31171 which might be worth
 looking at.

 Replying to [comment:20 ionic@…]:
 > You probably are right that the base OS X system (including ld and such)
 have been built *without* this feature. We may have just gotten lucky with
 GCC 4.5 working, even though this feature was enabled.

 Yes, I agree, that does seem to be the case. I don't see any evidence that
 the system libstdc++ is built with fully dynamic strings. It doesn't
 appear that way on my Lion system, and it sounds like it isn't on SL
 either.

 could fix their problem by enabling the fully dynamic string option.

 and produces libraries with this setting turned on by default, thus
 causing those kind of problems.

 I suspect the original problem was something else -- possibly related to
 _GLIBCXX_DEBUG.

 Unless anyone can come up with a reason not to, and assuming a couple more
 tests pass, I'll remove the --enable-fully-dynamic-string option.
