https://sourceware.org/pipermail/cygwin/2025-January/257025.html suggests the known problems in Cygwin 3.5.5 might be alleviated by rolling back to Cygwin 3.5.4: https://sourceware.org/pipermail/cygwin/2025-January/257085.html suggests this occurs after some step completes. Running the Python tests suggest the child processes are doing *something*, but attaching gdb to find out what fails: attempts to inspect the stack imply they converted the NULL pointer to a function pointer then called it recursively, which seems unlikely.
It'll take forever, but it might say which tests fail now.
Something's gone wonky with the threading/multiprocessing code. Not sure how to figure out what, since the debugger shows null backtrace.
Merge in upstream/main
Assumed minor version was a single digit when I wrote this: now checked to be a digit, and allowed to have one or two in the minor version.

The last four tests have hung just after |
Rust compilation also ran into segfaults during pthread_exit, and this is one of the fixes (the other was in libcurl, which python doesn't seem to use), so let's see if this resolves the issues.
I think libssl3 is actually the relevant bit.

The silent failure is still there. The sysconfigdata failure isn't, which means that's just on my system. |

Silent failure changed to a segfault, in probably the same spot. Not sure how to debug that, still. |
