Dimitry Andric 9ff1cc58cd Temporarily disable libunwind's FrameHeaderCache, until there is a ... resolution for <https://bugs.llvm.org/show_bug.cgi?id=47181>. The cache implementation depends on dl_iterate_phdr(3) ensuring that its callbacks are not called simultaneously for multiple threads, but that is only the case for the dl_iterate_phdr() implementation in rtld. In a statically linked executable, libc's dl_iterate_phdr() is used, which does no such locking. If multiple threads then call into the unwinder at the same time, it is possible to trigger a segfault. In particular, the statically linked lld which is built during the cross-tools stage can segfault in this way, because it starts multiple worker threads that can exit in parallel. Since our pthread_exit(3) invokes the unwinder, it will therefore call into it in parallel too.		2020-08-15 22:58:07 +00:00
