All, I'm not sure whether this should go to raspbain, debian or here. The package for valgrind for Rpi 3 (debian/jessie armf) is missing nearly all suppressions and will through over 4000 errors/warnings related to Conditional jump or move depends on uninitialised value(s) for just about every function that allocates or deals with allocated memory, (e.g. strchr.S:99, strlen.S:76, __libc_memalign (dl-minimal.c:66), memcpy.S:71, ....

I have attempted to update /usr/lib/valgrind/default.supp with files generated with valgrind --gen-suppressions=all, but I've been met with only limited success.

A valgrind check of a simple allocation results in over 2700 lines of warnings/errors:

That makes using valgrind almost impossible. The same code run with proper suppressions, has no warnings or errors (e.g. on openSuSE Leap, or Archlinux):

Just thought I would pass this along. If this needs to go somewhere else, let me know and I'm happy to move it.

Since we don't modify valgrind in any way, I believe this belongs here: https://bugs.launchpad.net/raspbian

Ok, I will move it.

Done, Re-filed as: https://bugs.launchpad.net/raspbian/+bug/1743293

This issue can be closed if that moved it to the correct tracker.

Is the package still unupgraded after three years? I am still finding valgrind to be not very usable on an rpi 4. Was this issue moved to the right place?

I don't know, I never received any feedback on it. Bug is still open and there are additional comments about the severity or impact. The last post there is some type of workaround, but the bug hasn't been fixed. That has been a rather long time...
