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

I've never seen these errors yet. Can you try to use "hg bisect" to find the changeset where the error was introduced? I know it's difficult with sporadic errors... Or maybe try valgrind? Regards, Johannes

I was hoping to avoid that, as it would probably be awfully tedious. I'll give it a go if nothing else works.
Or maybe try valgrind?
I've given it a few quick runs under valgrind but seen nothing helpful. Maybe I should just run it under valgrind continually. It's lucky Dillo is fast! Imagine trying to do that with Firefox. Regards, Jeremy Henty
