I have the following line of code in my codebase: [^${char}\\s][^${char}]*[^${char}\\s] (it’s used to build a regular expression). When I remove it from my codebase, @tailwindcss/jit works fine. When I add it back Tailwind CSS fails to build with:
RangeError: Maximum call stack size exceeded

I reproduced this issue by taking the implementation of candidatePermutations() in my node_modules folder and running it standalone:
function* candidatePermutations(candidate, lastIndex = Infinity) {
if (lastIndex < 0) {
return
}
let dashIdx
if (candidate.endsWith(']', lastIndex + 1)) {
dashIdx = candidate.lastIndexOf('[') - 1
} else {
dashIdx = candidate.lastIndexOf('-', lastIndex)
}
if (dashIdx < 0) {
return
}
let prefix = candidate.slice(0, dashIdx)
let modifier = candidate.slice(dashIdx + 1)
yield [prefix, modifier]
yield* candidatePermutations(candidate, dashIdx - 1)
}
for (const result of candidatePermutations('[^${char}\\\\s][^${char}]*[^${char}\\\\s]')) {
console.log(result);
}
