I have a backend linux process that has been getting sigkill by the kernel for memory (much to my surprise). This is a repeated issue. As such, I've been prompted to shoehorn my linux process into a signed MacOS binary so that I can profile with the nice tools on that platform.

I came into the profile test fully expecting my binary target to have a leak (as I'm using Unmanaged and a lot of other stuff)....but the verdict is clear, yyjson is the leaker.

See column right, according to my tools and application context, the leak is squarely in this yyjson_mut_write_minify function.

There may be other leaks but this is the one I'm hitting in my application, now on MacOS and Linux.

update: upon further inspection, the leak here was my responsibility. so I have no evidence to contribute towards a memory leak in yyjson.

the yyjson header documentation made it clear how I needed to handle this memory and I failed to stay in line.
