This was in previously working code which used dlopen on a library with pthreads. We used RTLD_LAZY | RTLD_GLOBAL to work around previous crashes but now we can't get the code to work unless we LD_PRELOAD the pthreads library first. I'm on libstdc++.so.6.0.28, gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
