--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- What I wrote were some approaches how to make symbols that aren't part of the libtsan.so.* ABI not exported from the library. If __interceptor_* functions are part of the ABI, as seems to be the case from what you wrote, then it is an ABI bug that it disappeared and it needs to be readded.
