Thanks for letting me know. I will check that.

Hmm. It looks like the postcss tokenizer source code is broken by minify. Broken postcss tokenizer loops infinitely.

[ota-meshi]

Hmm. Even with minify turned off, the necessary source code is missing in the build. I still don't know the cause of it.

Original:

          RE_WORD_END.lastIndex = pos + 1
          RE_WORD_END.test(css)
          if (RE_WORD_END.lastIndex === 0) {
            next = css.length - 1
          } else {
            next = RE_WORD_END.lastIndex - 2
          }

Output:

          RE_WORD_END.lastIndex = pos + 1;
          if (RE_WORD_END.lastIndex === 0) {
            next = css.length - 1;
          } else {
            next = RE_WORD_END.lastIndex - 2;
          }

I still don't know the cause, so I opened an issue on vite's repository.
vitejs/vite#11330

if it helps narrow it down, i'm pretty sure it was working properly until a few days ago

[ota-meshi]

I suspect that a major version upgrade of vite v4 or rollup v3 is the cause of the problem, but I'm not sure how to confirm that at the moment 😅
