g++-8.3.0 coredumps when building icestorm

This is just a heads-up. I don’t really want to take the time to debug this further, since it’s fairly straightforward to install g+±7, temporarily downgrade (via sudo update-alternatives), and just use that. Still, here is the error:

That’s just the way linux works, by default overcommit is enabled. So when you do a malloc you never get NULL you always get a valid pointer but when you try to use it, if the kernel can’t actually find any memory … it SIGKILLs the process. You can google “linux memory overcommit” for details.

Closing, due to be memory related issue and not icestorm related
