Andrew Kaster 723b8586ec CI: Enable UBSAN for on-target tests 
Note that until UBSAN is made deadly by default in LibSanitizer, UBSAN
warnings will not fail the build.

Also remove BUILD_LAGOM=ON from the NORMAL_DEBUG build as it's
unnecessary and extends the build time for no benefit when building with
sanitizers

SerenityOS

Graphical Unix-like operating system for x86 computers.

Build status Fuzzing Status Discord

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
