[Valgrind-users] Possible to suppress low block count loss records?

[Bresalier, R. (N. - US/M. Hill) <rob...@no...>]

We are trying to track down a suspected place in our code that keeps accumulating memory in a 'still reachable'.

When I turn on still reachable and run my process for a few hours and then stop the process to get the valgrind reports there are over 2.7 million loss records which are mostly still reachables. It would take forever for valgrind to print this out.

The large majority of "still reachable" that I want to ignore allocate just a few blocks. I would like to suppress these and only output "still reachables" that allocated 100 blocks or more.

The suppression mechanism seems to only be to suppress particular backtraces.

But I would like to suppress based on number of blocks instead, suppress loss records with a small number of blocks.

Is this possible to suppress based on block count without patching valgrind?

If not possible without patching valgrind, any hints on where I could patch valgrind to accomplish this?

Thanks,
Rob
