Comment # 12 on bug 1218365 from Brad King

I investigated this for the upstream cmake issue:

* https://gitlab.kitware.com/cmake/cmake/-/issues/25500#note_1468188

I reproduced it on a ppc64le virtual machine running Linux kernel
6.6.6.1-default with tumbleweed 20231219.

cmake 3.28.1 with libuv 1.44.2 works, but with libuv 1.47.0 it exhibits the
random crashes.

This bisects to a change introduced in libuv 1.45 to add io_uring support:

* https://github.com/libuv/libuv/pull/3952
*
https://github.com/libuv/libuv/commit/d2c31f429b87b476a7f1344d145dad4752a406d4

After locally patching libuv's uv__io_uring_setup to return -1, the crashes go
away.
