Set the depth of allocation backtraces to a specific number. The default value is 5. |
| MALLOC_EVENTFILE=file |
Advanced Settings
|
Target output file or device
|
Redirect the event output to a file.
The filename can contain ${pid} to add the process ID.
Use a hyphen (-) to redirect the output to standard output (the default).
