Qt WebKit 5.212.0 Alpha 4: crash application

[agarny]

Hi,

I am using Qt WebKit 5.212.0 Alpha 4 in my application and, apart from a known issue (discussed here), it has been working fine. However, I have just come across an issue on macOS. Basically, if I try to load https://lemonde.fr/ then it will load it fine, but then it will crash my application. On Windows and Linux, everything is fine with that website. Could anyone confirm? @Konstantin-Tokarev?

Just in case, I am on macOS Catalina (10.15.3) with Qt 5.12.9 and Xcode 11.5.

Cheers, Alan.

FWIW, everything works fine in my application if I use Qt WebKit 5.212.0 Alpha 3.

However, I have also built both Alpha 3 and Alpha 4 on their own, and checked https://lemonde.fr/ with MiniBrowser and QtTestBrowser and:

• MiniBrowser crashes uploading https://lemonde.fr/ and this with both Alpha 3 and Alpha 4;
• QtTestBrowser loads https://lemonde.fr/ fine (or so it seems), but will eventually crash when loading another page (after clicking on one of the links) on that website. This, using both Alpha 3 and Alpha 4.

So, I have no idea why https://lemonde.fr/ works fine in my application using Alpha 3, but it does...!?
