Fifth crashes when I try to go to any URL #28

Hi! I'm the maintainer of the fifth package in Gentoo. I built it (with its dependencies webkitfltk and urlmatch using GCC 7.3.0), and everything went fine. However, everytime I want to go to any URL, this happens:

Also, I tried with gdb:

I think the problem is with WTF.

Thanks.

It's known that webkit built with asserts crashes on most websites. The asserts are rather zealous, or if you prefer, webkit code is not up to the standards of the asserts. So for a production browser comparable to Safari or others, please disable the asserts; other webkit projects also do so.

I should also mention that LTO with GCC 7 causes issues, so you should disable LTO for that version in the ebuild, if that is possible.

@clbr In fact I don't have enabled LTO in GCC7, so I'll try disabling the asserts to see if it works. I guess may do it in both packages (webkitfltk and fifth)
