Context

I'm running macOS Catalina (Version 10.15.7). I recently downloaded the latest version of Valgrind, and now I see "???" for every source of leak. The previous version worked perfectly yesterday. Here are some logs:

==81957== TO CONTROL THIS PROCESS USING vgdb (which you probably

==81957== TO DEBUG THIS PROCESS USING GDB: start GDB like this
==81957==   /path/to/gdb ./minishell
==81957== and then give GDB the following command
==81957==   target remote | /Users/gdelvign/.brew/Cellar/valgrind/HEAD-93191c1/libexec/valgrind/../../bin/vgdb --pid=81957

What went wrong?

I ran Valgrind with the following flags on my program:

valgrind --leak-check=full \
	 --show-leak-kinds=all \
	 --track-origins=yes \
	 --track-fds=yes \
         --verbose \
         --keep-debuginfo=yes \
         --suppressions=readline.supp \
         --log-file=valgrind-out.txt \
	 ./exec

What did you expect to happen?

I expected Valgrind to show the source of each memory leak instead of displaying "???".

Information

  • macOS architecture (uname -m): x86_64
  • macOS version (sw_vers): 10.15.7
  • Xcode version (xcrun --sdk macosx --show-sdk-version): 11.1

Thank you for your help.

Hi @Gillian-Delvigne,

Did you build your binary using -g?

Sure !

I have found a little workaround. I changed your formula to get a previous (functional) version of your valgrind. I added system "git", "checkout", "d14be1d" if build.head? in the valgrind.rb file and now it is working again. So the d14be1d commit is working.
I'm part of the 42 network and the last version isn't working on any computer. I think this is about our macOS version.

Do you also get this problem with a trivial example (like Hello World)?

Quite likely an issue with ML_(check_macho_and_get_rw_loads). Linkers like mold have been giving us a hard time on ELF-based systems and the Valgrind code that assumed that ELF means one text segment and one data segment keeps breaking. Now the code is supposed to peek to see how many data segments there are and then trigger debuginfo reading when the text and required number of data segments have been loaded. The macho code is supposed to do the same thing.

I don't know if there is the MACH_HEADER and load_commands with DSC. Also it's quite possible that the fixed-size 4k buffer isn't big enough.

I backported that fix and it worked so this should be resolved once #122 is merged.

Thanks for the quick action. Unfortunately, it didn't help: :/

(The log output shows that this is indeed on af81aad with #122 merged)

So the d14be1d commit is working.

I can confirm this, I get normal output with this commit. In theory, I could git bisect this now, but it will be a PITA because the only Mac I have is the GitHub Actions CI... If you're interested, I may have the time to hack together a CI job that runs a script-driven git bisect, but not right now.

Of course, you use a Github amd64 macOS runner, so macOS 13.0. Let me adjust the version check and it should work.

Urghs, sure, I should have noticed that... Fingers crossed that it resolves the issue.

Thanks again. And by the way, nice to see the ARM64 stuff finally merged, even if not perfect!

I saw your GHA build and didn't connect the dots myself 🙄

Thanks again. And by the way, nice to see the ARM64 stuff finally merged, even if not perfect!

Thanks! Baby steps I guess... In case you do want to use it, I recommend you stick to macOS 14 on GHA as macOS 15 pretty consistently crash (https://github.com/LouisBrunner/valgrind-macos/actions/runs/13836067539/job/38711268799).
