Compiler issues on Current with ArcticFox browser

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hi All,

I have issues with "current" and ArcticFox browser (FireFox fork) I am 
developing. Unsure if it is a current issue or a pkg issue... or else.

Before the gcc switch, I was able to compile and run the browser, after 
the switch I can compile, but browser crashes on startup with no decent 
stacktrace

- system gcc 6.5 : compiles and works
- system gcc 7 : compiles but does not work

A curiosity, is that I never tested gcc7 because on Linux it failed to 
compile AF, so I limited myself to gcc 6.5 until the code improves. I 
installed it compiling it from scratch on current.

now one thing I thought is to get gcc 6.5 from pkgsrc, and try to 
compile, it fails!
So somehow the pkg compiler is not as good as the old system one? or did 
other things change in system that broke it?
