Description
For some reason, I can only reproduce this problem on Linux.
To reproduce, follow these steps (e.g. in a Docker container with docker run --rm -it node:20 bash):
# Get an example ReScript project, using rescript-core here.
git clone https://github.com/rescript-association/rescript-core.git
cd rescript-core
# Make sure a current ReScript version (11.1+) that has -warn-error is used
npm install rescript
# Create a source file with warning +32 (unused value)
echo "let unused = 1; let unused = 2" >src/Repro.res
# First build (warning, but no error -> ok)
npx rescript build
# Second build (warning as error -> ok)
npx rescript build -warn-error +32
# Third build (warning as error -> WHY???)
npx rescript build
