[Bug libstdc++/104852] std::[j]thread::detach() still gives segmentation faults with glibc 2.34

[Bug libstdc++/104852] std::[j]thread::detach() still gives segmentation faults with glibc 2.34
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104852 --- Comment #4 from Jackson Huff --- (In reply to Jonathan Wakely from comment #2) > For distros other than Red Hat (and Fedora, CentOS etc.) you need to use: > > -Wl,--whole-archive -lpthread -Wl,--no-whole-archive > > Otherwise the pthread symbols do not get pulled in by the linker. This would seem like a fix, but applying those flags to both the ADD_FLAGS variable and both manually specifying then in CMakeLists.txt made no difference (I tried variations for hours but no dice).

[Bug libstdc++/104852] std::[j]thread::detach() still gives segmentation faults with glibc 2.34
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104852 --- Comment #1 from Jackson Huff --- Note that my CMake command includes -lpthread even though CMake has been configured to link it already with -pthread, so when reproducing it, remove -lpthread to better replicate the situation (I only realized this after posting).

When I statically link it, I always get a segmentation fault for what seems to be something in the libpthread library. This happens with both std::thread and std::jthread. ldd --version shows a glibc version of 2.34 (specifically 2.34-0ubuntu3.2), and ld --version shows 2.37, both versions at which this bug should have been fixed. Here's the output of g++ -v: Using built-in specs.
