Auto merge of #674 - RalfJung:exceptions, r=Mark-Simulacrum

add another exception

This failed with the same error in both runs in rust-lang/rust#104429.

Doesn't crater run both builds in the same clean environment? We seem to have a bunch of cases of "baseline always works but try build always fails". It almost seems like the 'try' run can see artifacts created by the baseline, and that breaks quite a few poorly written build scripts out there.
