Doesn't crash for me, so I'll need a backtrace to be able to help.

To get a backtrace, you need to build Fifth (and maybe webkitfltk) in debug mode, and run it in gdb. There's good instructions online if you haven't used gdb before.

Hi, I also get crashes with YouTube:

wcout,

your crash is deep in cairo, which would point to it being a bug in cairo. Please install cairo's debug package, re-do the backtrace, and report to cairo.

[wcout]

My cairo version is 1.13.0 from the Ubuntu 14.04 packages. Do you have a different version ?

[clbr]

My cairo version is 1.13.0 from the Ubuntu 14.04 packages. Do you have a different version ?

Yes, I'm using the latest 1.12 stable, 1.12.18. Ubuntu's 1.13 appears to be actually older than that.

But obviously you'd need to try the most recent cairo before reporting a cairo bug, that'd be 1.14.0 or cairo git.

[wcout]

I fetched cairo git and built fifth to use it ==> this error is gone!

Got another one instead when moving around in YouTube (but far more less frequently) - some assertion in WebCore:

ASSERTION FAILED: !s.escaped() platform/text/SegmentedString.cpp(169) : void WebCore::SegmentedString::append(const WebCore::SegmentedString&)

As mentioned in the README, using a build with asserts is not recommended for normal use. It's mainly useful for webkit development.

[wcout]

Ah! Well, this section in the README was added after I first pulled the Repo ;) Anyway I don't really understand it. Does it mean I should modify the Makefiles or set some environment variable before compiling?

[clbr]

Before compiling, run

export CXXFLAGS="-DNDEBUG"
