I'm developing on Linux/g++ and uses valgrind to verify memory usage. My question is: How do I know where there is an allocation of memory in my application (including system libraries)? May be valgrind provides this functionality, or some similar tool.

When you run valgrind, it should tell you where there is allocations/free's – Tony The Lion Nov 12 '11 at 00:10

Or do you want to track this yourself? Your question isn't very clear. – Tony The Lion Nov 12 '11 at 00:10

If no memory error (allocs == frees), then no messages about memory usage, but I want to know about allocations in any case. – Andrii Nov 12 '11 at 00:19

... and where it happens – Andrii Nov 12 '11 at 00:19

If you want to profile memory usage, have a look at massif (valgrind tool). Also try the excellent massif visualizer to visualize the results.

gdb will allow you to monitor a specific memory section for writes and reads. You can set a break point on this. You can use the gdb 'watch' command.

I think you are looking for --trace-malloc=yes.

Yes, it looks like what I need, but output looks like "_Znaj(128) = 0x42FF060". Can I show it as a more readable? – Andrii Nov 12 '11 at 00:41
