Description

  • Version: 1.45
  • Platform: openSUSE Tumbleweed ppc64le (kernel 6.6.7-1-default)

We have been tracking a segfault found in the cmake test suite [1], [2] on ppc64le systems and have tracked it back to the introduction of io_uring support in libuv https://github.com/libuv/libuv/pull/3952

Research direction

Start by reproducing the cmake test-suite segfault on openSUSE Tumbleweed ppc64le with kernel 6.6.7-1-default, then inspect the io_uring support introduced by libuv pull request 3952. Use the linked openSUSE and CMake reports to compare the failure; done means the test suite no longer crashes on ppc64le.
