Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-09-26 13:38:51 UTC --- If you have a memcpy prototype and -fvisibility-hidden, without any pragmas around the prototype tweaking the visibility, then this is IMHO a user bug, as he promises then that memcpy is defined in the current shared library. To use -fvisibility-hidden with standard headers, one needs to surround them with pragmas.
