valgrind: mmap-FIXED(...) failed in UME (load_unixthread1) with error 22 (Invalid argument) errors on macOS

[abathur]

I'll describe the immediate problem first, but see the additional context section as well; I've found a macOS-specific fork/port, so I'm curious if anyone has used Nix-packaged valgrind successfully on macOS (and, if not, if using this fork as the source on Darwin may save some pain)?

Describe the bug
Most of my genuine invocations throw mmap errors. Note that I'm using the nulgrind/none tool to demonstrate that this looks like general valgrind behavior, but I see the same behavior on all ~4 tools I've tried.

$ /nix/store/vaw3azxwfqyr96j8j0x4yswwnywf3c2b-valgrind-3.16.1/bin/valgrind --tool=none /bin/cat
valgrind: mmap-FIXED(0x7fff5f400000, 8388608) failed in UME (load_unixthread1) with error 22 (Invalid argument).

$ /nix/store/vaw3azxwfqyr96j8j0x4yswwnywf3c2b-valgrind-3.16.1/bin/valgrind --tool=none cat
valgrind: mmap-FIXED(0x7fff5f400000, 8388608) failed in UME (load_unixthread1) with error 22 (Invalid argument).

$ /nix/store/vaw3azxwfqyr96j8j0x4yswwnywf3c2b-valgrind-3.16.1/bin/valgrind --tool=none jq
valgrind: mmap-FIXED(0x7fff5f400000, 8388608) failed in UME (load_unixthread1) with error 22 (Invalid argument).

$ /nix/store/vaw3azxwfqyr96j8j0x4yswwnywf3c2b-valgrind-3.16.1/bin/valgrind --tool=none /nix/store/mbahl5am0rx7aqf0z2wg34vvcld7124y-jq-1.6-bin/bin/jq
valgrind: mmap-FIXED(0x7fff5f400000, 8388608) failed in UME (load_unixthread1) with error 22 (Invalid argument).

No clue why the below two run. I've tried a few dozen programs so far and ps is the only one I've found that it runs for (perm error expected, SIP).

$ /nix/store/vaw3azxwfqyr96j8j0x4yswwnywf3c2b-valgrind-3.16.1/bin/valgrind --tool=none ps

To Reproduce
Steps to reproduce the behavior:

1. nix-shell -p valgrind --command "valgrind ls"

Additional context

• Basic invocations like valgrind --help and valgrind --version work.
• The Homebrew package for valgrind doesn't work on newer macOS versions, but I found an SO answer that mentions the https://github.com/LouisBrunner/valgrind-macos fork/port. I've installed this version via Homebrew following suggestions in that answer and it appears to work (has handled everything I've thrown at it so far.

Notify maintainers
Since I wonder if anyone's successfully used it on macOS, I'm also pinging some people that I've seen in #nix-darwin just in case anyone knows... @cransom @LnL7 @matthewbauer @thefloweringash @emilazy @burke @alyssais @eraserhd @toonn @dhess
