As I recall,  it compiled OK, but any use of javascript crashed the browser, we'll see what happens. Maybe a fresh review of the v8 code will highlight some problems <shrug>

<sigh> dooble crashed immediately, simplebrowser gives crashes like  the following...

This one looks familiar.  Didn't you already patch blink::ParkableImageManager::Instance() to do proper SSE alignment?

TBH I didn't even look at these last night, I was done for the day by the time the build finished. I'll  examine them this evening. It's always possible I missed a patch.

OK I patched around the SSE problems in blink::ParkableImageManager::Instance() - in this case, I just disabled SSE in this source file.

Now pages without V8 load, anything with javascript gives TRPs like the attached. As I recall, this is where I got to with Qt6.4.3 previously. It's hard, as every trp is different....

Most likely due to the changes in platform-os2.cc at https://github.com/psmedley/qt6-webengine-os2/commit/2df03acbb089c8472ca02f7477001780ad095dd0#diff-cc2c94e34243ed90f8fb8d01c931f30835818dc27a48275bb911a144f5bbf065
