About official apk repo php81 segmentation fault

[raymond-pineapple]

I'm not sure if this issue should ask here. But it seems just happen in ish (or Alpine Linux).

I have an issue on php81 which installed from official apk repo. I changed the apk repo by following the links:
https://github.com/ish-app/ish/wiki/Using-Alpine-Linux-repositories

And when I tried to install composer from link https://getcomposer.org/download/, I got "Segmentation fault". After some investigation, the problem is from code that including "===" with "getenv" or "strpos", like:
if ('Hyper' === getenv('TERM_PROGRAM')) {

But only "===", "getenv" or "strpos" will not trigger segmentation fault.

Before trying official repo, I use ish self repo to install php8, which can perfectly install composer.

Since I have no any clue on which party should ask, I just raise the question here to see if someone can help me. Thanks
