Hello, the boost library (1.66, quite outdated) is wrongly built for cygwin regarding the 'context' lib, in a way that makes the 'coroutine2' lib crash.
b2 should be called with "context-impl=ucontext" argument when building it. And programs using boost context/coroutine2 should build with the flag -DBOOST_USE_UCONTEXT These options are documented at the bottom of this page: https://www.boost.org/doc/libs/1_75_0/libs/context/doc/html/context/architectures.html And that would fix the problem here reported for the nix program. https://github.com/NixOS/nix/issues/4360 Can someone make that fix? I haven't tried explicitly 1.66 with that build flag, but 1.75 failed the same way until I added that build flag.
