Some annoying compilation issues

Some annoying compile time issues. I am compiling on various Linux platforms. Just passing along because they seem to spit up a lot. Please add to the never ending to-do list. I don't do anything with JavaScript, but that one seems like it could cause all sorts of hardship.

Thanks for mentioning this, please know we are aware of these issues.

(1) src/3rdparty/javascriptcore

There are a number of JavaScript files in the which are part of the "third party libraries". The one you mentioned has a format issue and we have also seen zeros which should be a nullptr. We would prefer to update these files through the vendor instead of changing them directly.

(2) include/QtCore/qcoreevent.h

We have assigned this to someone on the team and they will trace through this one.

(3) qharfbuzz_gui.cpp

We are about to update the Harfbuzz library which will involve changing all of the support files.

Thanks again for your information and we will keep you updated.

Barbara
