Systems programming languages with GC (any form of automatic memory management), also provide features for doing manually memory management, explicitly releasing resources, allocating on the stack or the global memory segment.

Depending on what one is trying to do, those constructs can still be allowed on safe code, or require explicit unsafe modules (or code blocks).

Examples, D, Nim, Swift, Mesa/Cedar, Modula-2+, Modula-3, Sing#, System C# (aka M#), .NET (version and language dependent).
