--- Comment #9 from Tomasz Kamiński <tkaminsk at gcc dot gnu.org> --- Looking at the logs, it looks like the problem occured during bisecting, in combination with use of PCH: /home/kishan/CI/manual_bisecting/gcc/libstdc++-v3/include/precompiled/stdc++.h: I wonder, if the PCH may be built from previous commit, and does not include the pragmas. Could you please confirm that the problem does occur for clean built on trunk (or any commit after this change)?
