LibResilient crashes on iOS in Lockdown mode?

[link2xt]

The problem was reported on Mastodon.

Upstream LibResilient issue: https://gitlab.com/rysiekpl/libresilient/-/issues/87

Need someone with iOS to reproduce. We can patch it locally and then upstream once we know how to reproduce it.

• safari iOS private mode on iOS 18.4.1 is working for me
• firefox klar 141.0 (=german firefox focus) on iOS 18.4.1 is working for me
• safari macOS 18.4 private mode on macOS 15.4.1 is working for me

maybe more specific to some safari/macOS version?

maybe more specific to some safari/macOS version?

From Mastodon:

iPadOS 18.6; the error is shown in both Safari 18.6 (20621.3.7?) and Firefox Focus 141.0 (58086).

Playing around a bit with settings, it appears that iOS’ Lockdown Mode is the cause. The website works normally with it disabled, and also works and continues to load correctly if I initially load the website (and in turn the service worker?) with Lockdown Mode disabled and then reenable it.
