--- Comment #21 from Tom Hughes <t...@compton.nu> --- Hmm.. It doesn't seem to make a huge amount of sense. Both versions of Qt are using PIDFD but with 6.1 the FD we get from the kernel seems to be a silly number that is not a valid file descriptor triggering everything which follows. The final failure is because we set SfYieldAfter in the flags even though we have syntheised an EMFILE error for the invalid descriptor. The actual kernel clone has happened though so it's not clear that we can synthesise an error in POST like that though - it's all a bit tricky. None of that explains the FD we are getting from the kernel though, or the difference between Qt versions. I wonder if the kernel is not writing it at all and the value we are seeing is what happened to be in that location before the call. Can you get an strace of both versions running under valgrind so we can see how the kernel level clones compare? -- You are receiving this mail because: You are watching all bug changes.
