Description
On a x86-64 target based on Yocto Nanbield and Qt 6.6.2 I see on a specific web page(https://developer.mozilla.org/en-US/docs/Web) renderer process crashes.

On an other target based on a i.MX6 this works w/o issue.
I also tested this on my Desktop(Arch Linux based) and there this doesn't seem to be an issue either.
I tried to debug it and ended up with this backtrace:
Thread 1 "QtWebEngineProc" received signal SIGSEGV, Segmentation faultwarning: could not convert 'v8::internal' from the host encoding (UTF-8) to UTF-32. This normally should not happen, please file a bug report.

I also tried using the QtWebEngine library from my desktop, and surprisingly that also worked without any problems.
