That could be related. I don't know enough about llvm's profiling to say. If it's just a warning and not terminating the process, that might be OK. But some of the tests check the stderr from Git. If the profiled binaries are producing extra messages, that could cause a problem (and it looks like t0410.15 that you posted does make sure stderr is empty, so this seems a likely culprit).

They're generally run with whatever $SHELL_PATH is set by the Makefile knobs, which defaults to /bin/sh. The interactive shell you're using shouldn't be relevant.
