> Our other bots are not failing, so I very strongly suspect this is not because of the change itself, but rather some weirdness in your bot configuration. For that reason, I will *not* revert the change (that would likely not improve the situation anyway). Can you please collaborate with us to understand and fix the issue?
Also, is there a Docker image used to run the bots? That is our preferred way of handling libc++/libc++abi bots, because that means anyone can reproduce the failures locally. If the bots don't require anything specific beyond the CMake configuration they're testing, you could even use our existing Docker images based on Debian.
