<pre>I'm failing to come up with a minimal reproducer right now,
but if a program is built with threading (-fopenmp),
and does some work in threads, then even though the 'llvm-profdata merge'
does not complain, the `llvm-cov show` fails with:
error: <binary>: Failed to load coverage: Malformed coverage data
I *thought* it worked before. Is that expected/intentional behaviour?
This is with llvm/clang trunk.</pre>
