Unlike C11 atomics, C11 threads do not share an ABI with C++’s<thread>facilities, but C++ programs can include the C11 threads header and call the functions just like any C program. Both are implemented in terms of the primitives provided by Windows, so their usage can be mixed in the ...
Trivial C11 threads.h implementation over POSIX threads, and not-so-trivial implementation over Win32 threads. Rationale Even though GCC provides the threading features required by the C11 standard (like atomics, and thread-local storage), GNU libc, still does not implement the necessary library fu...

It seems to be primarily on Windows; A recent example is here but most recent failures are this issue. 4 of the 50 most recent WIndows CI builds failed with this issue.

C11 (ISO/IEC 9899:2011):发布于2011年,C11标准在C99基础上进一步完善,加入了对多线程编程的支持(通过<threads.h>库)、增强了Unicode支持(通过<uchar.h>)、引入了原子操作和线程内存模型、静态断言、匿名结构和联合、宏默认参数等新特性,并提高了语言的安全性。
