When adding the memory tracepoints (after applying the fixes for QTCREATORBUG-25651) and using those tracepoints for a performance analysis, the memory usage statistics don't show up in the Flame Graph.

The samples for the flame graph (which I presume are the calls to malloc, free, etc.) show up, and are very different compared to the results when using the default CPU counters. However, the "Peak Usage", "Allocations", and "Releases" portions of the flame graph are all empty.

Some modifications to the tracepoint script (QTCREATORBUG-25651) were required to get the tracepoints properly added. My guess is some changes in the recent versions of the perf tool prevent the statistics from being parsed properly.
