server unsafe code audit: fixed memory leaks and other violations#364
Conversation
Multiple fixes were applied: - Memory leak in `FixedVec` due to zero length free - Possible unsoundess in use of moved boxed slice pointers - Fixed user-after-free (UAF) in ordered idx impl I'm further working on finding and fixing other sources of safety violations; even though they may not be "major" but we must steer clear of them (such as miri SB violations).
Also note that we now properly classify tests based on leak severity for the generic audit routine.
Due to the amount of single core burn miri needs, it is almost impractical to run it on every commit with our currently allocated CI resources. We may revisit this in the future.

This is good to go; fully tested locally (impossible to run on CI). @glydr r+ |

Fixed a bunch of memory leaks (mostly very low impact since a majority of them only happen at startup time and don't change throughout) and some possible violations resulting from
noaliasoptimizations (rustc -> generated LLVM IR) for unique pointers in std.Unsafe code audit for Q2 2024 stands complete.
