This

https://raw.githubusercontent.com/boostorg/uuid/feature/gcc_pr_114865/test/test_gcc_pr114865.cpp

exhibits the problem for me on GCC 13/14. I'm only seeing the hang with
-std=c++11 -m32 in the CI run because this combination is tested first, but I
believe it's independent of standard level and address model.
