Intel® Inspector
 is a dynamic memory and threading error checking tool for users developing serial and multithreaded applications on Windows* and Linux* operating systems. This topic is part of a
tutorial
 that shows how to find and fix
threading
 errors using the
Intel Inspector
 and a
C++
 sample application.

Interpret Sources Window Pane Tabs

A
Sources
 window similar to the following displays after you double-click the data row for the first
Data race
 problem in the problem set. It provides more visibility into the cause of the error.
Sources window
1
The
Source
 tab shows the complete source surrounding one code location in the
Data race
 problem. (Samples are non-deterministic; you may see a memory
Write
 or a memory
Read
 code location.)
2
The
Disassembly
 tab shows low-level operations for the code location in the
Data race
 problem.
3
The
Call Stack
 tab shows the complete call stack for the code location in the
Data race
 problem.
4
This region shows source, disassembly, and call stack information for another code location in the
Data race
 problem. (Samples are non-deterministic; you may see a memory
Write
 or a memory
Read
 code location.)
Use the Expand control /Collapse control icons to expand/collapse source, disassembly, and call stack information for each code location region in the
Data race
 problem.
