--- Comment #12 from Jason Merrill <jason at gcc dot gnu.org> --- (In reply to Dave Johansen from comment #11) > Can this please be reopened? It was determined in the glibc bugzilla that > this is a gcc problem because of the incorrect setting of unique flag. The setting is not incorrect, nor is it an optimization; it is necessary to fix the behavior of RTLD_LOCAL with multiple loaded objects depending on the same library, since the glibc developers rejected the other approach that I suggested (https://www.sourceware.org/ml/libc-alpha/2002-05/msg00222.html). If you don't need this handling, in 4.9 you can use -fno-gnu-unique to disable it. I'll go ahead and backport that switch to 4.8 as well.
