It took me a couple of days I didn't have to workout which commit caused it, which versions showed the issue and how to work around it. It looks host kernel specific since it doesn't happen on some systems so even with the binaries/command/environment vars, it may not be enough. I was hoping the indication of the cause might help point to the fix as there is quite a bit of work in trying to extract this into a reproducer. The failure is 20 mins into a webkitgtk compile on a remote CI system which no longer has the context on it. > Please extract a binary to run, inputs, and command-line. I wish I could say that to the bug reports I get! :) I'll do my best but finding the time is going to be a challenge. Cheers, Richard
