Semantic Analysis Out of Memory when testing std.zig

[iacore]

Zig Version

0.10.0-dev.40+303bad998

Steps to Reproduce

1. Use a machine with only 2GiB of memory
2. Clone and enter zig repository
3. run zig test lib/std/std.zig --zig-lib-dir lib

It's possible to test each package individually, but not together. It seems like Zig does not garbage collect in "Semantic Analysis [...]" phase.

Expected Behavior

The command should work without using too much memory

Actual Behavior

zig being killed by kernel for out of memory
