thread 'main' panicked at 'unexpected file ...'

[osa1]

Using master branch (e4e5da4)

In a clean tree, if I run

./target/release/collector \
    profile_local \
    self-profile \
    /home/omer/rust/rust/build/x86_64-unknown-linux-gnu/stage1/bin/rustc \
    test

I get this output:

This looks like it was fixed by commit 4fa8ee6 of #865.
