Crashes in dw::core::Layout::createImgbuf()

by onepoint＠starurchin.org

For the last few days I have been getting occasional crashes inside dw::core::Layout::createImgbuf() when opening a new tab. It does not seem to be predictable: if I restart Dillo and reopen all the URLs I was just looking at it is fine. The gdb backtrace often shows ridiculous values for this: eg. the attached example has this=0x6. I've seen other impossibly small values for this, but sometimes the value seems more sensible. Any ideas? I'd like to investigate further but I don't know what to look for. Pointers are welcome! Regards, Jeremy Henty

Yes, I have a combinatorial case table of things to manage, some work some doesn't. The idea is to get to a design that handles them cleanly. BTW (@all), the "tools" button is 60% done, but stopped. As it also uses repush to enable/disable CSS parsing, is better to fix the above issues before testing it. -- Cheers Jorge.- ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.

No, we can easily change the default fontsize to 14. If nobody objects, I will make that change later today. Cheers, Johannes

Yes, there were cleanups on charset decoding.

Before that fix, starting dillo with valgrind "solved" the problem and shows some invalid reads and writes. Now these invalid reads and writes are gone. Greetings Andreas Kemnade
