I created by accident a copy of the file and rescript build went in to panic
This is enough to reproduce:
$ tree src
src
├── a
│ └── Test.res
└── b
└── Test.res
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
error Command failed with exit code 101.

Is this already reported as a bug and/or fixed?
