retdec-decompiler fails on macOS 12

[catap]

When I try to decompile any binary on macOS 12, it crashes:

libc++abi: terminating with uncaught exception of type std::runtime_error: failed to limit maximal memory to half of system RAM

anyway, --max-memory 0 works fine

Hi, this issue is somehow related to #379. The issue in #379 is that setting a limit on macOS is not doing anything. In your case it is doing something - failing :D

I'll try to look at this on macOS 12 myself. The fallback "hack" is that I'll set the option --max-memory to 0 by default on macOS (as it is not doing anything right now, see #379). But I'd rather see it working properly.

Workaround no longer works:
Error: Invalid value for --max-memory: 0 (expected a positive integer)

@weareu Could you please provide us (1) the decompilation command that you have used and (2) the full output from it? I have just tried passing --max-memory 0 to retdec-decompiler and it worked without any issue (current master).

--no-memory-limit works as workaround for me on macOS

Funny things, I've started to implement "a fix" on last December (when I've created and issue) but never had a chance to test it.

Let me finish it :)
