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 !
cc -g -O0

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.

Good point @paulfloyd, I had such an issue on arm64 with some read-only segments having the wrong protection (no idea how that's possible) which was messing this up. Hopefully that will be fixed after the merge.
