Gunnar Beutner ea33e9647b LibC: Don't leak memory for realloc(p, 0)
Previously we'd leak memory when the user called realloc(p, 0). Instead
this call should behave as if the user had called free(p).

SerenityOS

Graphical Unix-like operating system for x86 computers.

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.
