Segmentation fault #45

Open ghost opened 5 years ago

ghost commented 5 years ago

When orayta is running, and I click randomly inside the text window, it crashes. If run from the terminal, it says Segmentation fault. This occurs both when using the precompiled binaries, as well as when I compile it myself.

I did some more testing, and it appears to be caused by libQt5WebKit.so.5, which is also giving others some issues as well (and possibly related to this). I'm in middle of compiling the latest QtWebKit, and will update if it works when it finishes compiling.

This issue doesn't appear when compiled against Qt4, and even Qt5 if running within gdb or valgrind.

It finally finished compiling, and now this is what I get:

Thread 1 "orayta" received signal SIGSEGV, Segmentation fault. 0x00007ffff59d0506 in unsigned int WebCore::WidthIterator::advanceInternal(WebCore::SurrogatePairAwareTextIterator&, WebCore::GlyphBuffer*) () from /usr/lib/x86_64-linux-gnu/libQt5WebKit.so.5

And the backtrace:
