Unfortunately I can’t get to this right now, but will take a look first thing tomorrow morning.
A shot in the dark: looks like your workflow causes a clang process to be sent SIGPIPE more than once. The second time, it exits with ioerr. I expected this to be the pre-patch behavior, so I’m confused as to why the reverts appear to help.
If you need a quick fix, I’d suggest adding a SIG_IGN for SIGPIPE to the clang driver. Those reverts could regress lldb and I’m really not sure why they work.
