This is effecting me as well, in fact it is impossible to declare a variable with a destructor as thread_local without a getting a segfault. Tested with x86_64-6.3.0-win32-seh-rt_v5-rev2 and x86_64-5.4.0-win32-seh-rt_v5-rev0. A simplified test case is: #include <iostream> #include <vector> int main() { static const thread_local std::vector<int> two(2, 3); std::cout << two.size() << std::endl; return 0; } Which will segfault on program exit. There is a workaround, which is to link to the static runtime...
