--- Comment #1 from Kostya Serebryany <kcc at gcc dot gnu.org> --- Interesting. tsan in clang works, so we either have problems in the gcc build system or we have some differences in the code that affect the sigsetjmp interceptor. one other problem would be that we have zero tests for tsan in gcc :(
