Illegal Memory Access

(LOCAL:MEMORY:ILLEGAL_ACCESS)

This feature depends on valgrind the same way as LOCAL:MEMORY:INITIALIZATION. This check goes beyond LOCAL:MEMORY:ILLEGAL_MODIFICATION by detecting also reads and reporting them through valgrind at the point where the access happens. Disabling it might improve performance and help if the provided suppression rules do not manage to suppress reports about valid accesses to locked memory.

Call Graph

The Call Graph tab shows a small part of the call graph for each process or process group: a single node (called central function) with its inbound and outbound edges. Each process entry has three children: the Callers, the central function, and the Callees.

Navigating through the Call Graph, double-click on a caller or callee and press the space bar or the Enter key to select the respective function as the central node.
