Current and arcticfox crash

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

Hi All,

I'm trying again an update of ArcticFox on NetBSD (PaleMoon/FireFox 
derived browser).
Previoulsy I got it running with Maya's suggestion to do a "paxctl +m" 
on the generated binary. It was enough to get it running, although I got 
glitches.
Today I tried again.

1) I have updated kernel, userland, compiler, everything. We are running 
on gcc 7.4!
2) all pkgsrc was updated too
3) there were some changes in the meanwhile in ArcticFox, which still 
does fine on linux, mac and openbsd though...

Compilation succeeds, however it crashes on startup, with a cryptic 
stacktrace

Starting program: /usr/local/bin/arcticfox
[New LWP 1 of process 13722]
[New LWP 12 of process 13722]

Thread 2 received signal SIGTRAP, Trace/breakpoint trap.

#2  0x00007f7fffd58370 in ?? ()
#3  0x0000000000000000 in ?? ()


Now... understanding what broke is hard.


First thing I think of is the compiler, on other platforms gcc 7 failed 
to compile ArcticFox, I wondered it completed at all, maybe some fixes 
in the source code helped.
;aybe it compiles but causes issues?
Can I get gcc 6.5 from sources easily, to exclude that parameter? having 
a whole new userland+pkgsrc is a big change...

Help!
