Doesn't Xcode come with the "Instruments" application which is designed to do
the things that OP is asking about? I have used it in the past for function

Elvis,
I have just tried that it resulted in this. I’m not familiar with valgrind
output. Does this look good to you?
--45024-- UNKNOWN mach_msg unhandled MACH_SEND_TRAILER option
--45024-- UNKNOWN mach_msg unhandled MACH_SEND_TRAILER option (repeated 2 times)

I used valgrind with valgrind --tool=massif myApp to track down a memory
issue just today actually, and it worked out great, but I don't know if it

I've been meaning to check out heaptrack but haven't gotten around to
Hasn't valgrind been unable to work since 10.11 or something like this
though because of kernel restrictions ? e.g.

And people have ported applications to Linux just to be able to use it.

I've tried more than once with Valgrind, but never got it working with
QtCreator on macOS. Just tried it now and:
Failed to start program. Path or permissions wrong?
