Potentially uninitialized variable

[Wizer21]

Hello !

I have a warning saying that a variable is not initialized in the shader, when it appears, the browser freezes for 10-30s.
I've tried several examples from the library, this doesn't seem to be the issue.

The issue seem's to be similar to the post #325

It sometimes appears on chrome and edge.
But for my computer i always have it on firefox, no matter the version.
I also had it on other computers.

Graphic card NVIDIA GeForce RTX 3070 Ti Laptop GPU
Processor 12th Gen Intel(R) Core(TM) i9-12900H 2.50 GHz
Chrome 128.0.6613.85
Edge 127.0.2651.105
Firefox 129.0.2 ( also tried 128/125/115/105 // v105 was published the 18-Mar-2023 )

It was definitely working in previous version so if previous versions aren't working on Windows now then there's been a new regression or change with without any useful logs. Can you check this examle and this example? Otherwise tracking these kinds of errors down is a nightmare.

the browser freezes for 10-30s.

Unfortunately this is a known Windows issue we have no control over due to the shared compiler being used used under the hood. See #325 (comment).

The first time I opened them, I had this problem. But it never happened again, even when I restarted the computer, cleared the cache or used private browsing.

Looking through those functions in three-mesh-bvh briefly I don't see anything that sticks out as an issue. The first step would be figuring out how to repro the warning consistently so we can make sure it's been fixed. Changing the shader string slightly may force a recompilation even if clearing cache isn't removing the shader for whatever reason so we can see the error reliably.
