Kind of a mess since you can take a system down with this.

 Obviously peoples are running firefox on netbsd-8 (I am) so we'll need more
 details about it. E.g. which pkgsrc version ? does it die in firefox
 itself or one of its dependancy ? Any panic message ?
 Anything in /var/crash ?

 I moved this to port-amd64. It's whatever's in that directory as of
 pkgsrc-2019Q1. "lock up" means "lock up" and that means nothing in
 /var/crash and since I was doing it remotely, nothing saved.

 What are the last lines of output? What is your build machine?
 What settings did you use (like MAKE_JOBS) or anything special in
 mk.conf? Enough swap? Did it still ping? Did you try to enter ddb?

 Since I'm using tmux, and trying to do other work, the output is gone.

 MAKE_JOBS=12
 tmpfs is 2G

 no ping

 locked up means locked up and the keyboard did nothing so I didn't try
 entering ddb. I don't think the console even lit up. I had to hit the
 reset button.

 This doesn't tell us how much ram and swap you have configured.
 With MAKE_JOBS=12 and such a big c++ software it's possible that you ran
 out of ram

 So you have 6GB ram, right ? With 4G swap that is about 10Gb of virtual
 memory; it may be a bit short for make -j12 ...

 I disagree - even if this is overcommiting, the system should not lock
 up. Is this reproducable? What is your tmpfs usage in the pkgsrc build?

 You really make it hard to analyze by giving tiny details piecewise ;-)

 Basically we need someone with a proper debug environment to reproduce
 your issue, and then reproduce it again with test kernels over and over
 to verify potential fixes, so please describe in more details what you
 are doing!

 I can reproduce this issue (I did it three times), but on a production
 server. Not going to do that again, if I can avoid it.
