It priority problem was described.

Q: I only get trp files using the LIBCN0 as suggested. Is it as expected ?

I have a case having the trp all times, here's one more trp

If these are silent exits - then yes. Silent exit is caused by  the webengine code calling exit(). The modified libcn0.dll  modifies  the exit() code to force an exceptq dump.

The TRP will include "Cause:    Program requested an Exceptq debug report" whereas a 'normal' exceptq will show something like "Cause:    Invalid execution address 00000000"

Now that the 6.2.6 webengine is working ok-ish -  I'm rebuilding the 6.2.8 code which is chromium 102.0.5005.177, using GCC 14. This is similar to the code in Qt 6.4.x.

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>

Hi Paul,
Something I observed is that when changing youtube video on the fly during play, system sound is impacted and no more available until WPS restart. (ArcaOS uniaudio used). Have no idea why

<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?

Hey Steven,

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

It's a known issue with all versions of Qtwebengine.

You left out one 'f' in ffmpeg.

https://smedley.id.au/tmp/ffmpeg-chromium-6.3.2-20230516.zip works!

I updated the core Qt6 libraries to 6.2.10  which was released this week.  The webengine remains at 6.2.6  due to javascript issues.
