Sometime the user met a software crash, but the developer can't reproduce such problem on their side. So if the user can generate (provide) core dump file then submit a new issue to https://premier.intel.com with this file, it will beneficial on bug fix.
- Right-click on "My Computer", then click "Properties"
- Click on "Advance" tab
- Under "Startup and Recovery", click "Settings"
- Under "Write debugging information", select "Small memory dump (64KB)"
- Default directory "C\Windows\Minidump" for "Small dump directory:"
- Click "OK" button.
- Use regedit.exe to verify item named "CrashDumpEnabled" value is 0x3 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
- Restart the machine
- If software crash happens, Minixxxx-01.dmp will be generated
Note: usually developer uses WinDbg to know what and why caused this failure.
1. Use "ulimit -c" to check the switch of generating core file. If result is zero, the switch is disabled, will not generate core file
- Use "ulimit -c filesize" to enable this switch (filesize is KB), or use "ulimit -c unlimited". Using filesize might cause file truncated, gdb will report error.
- If the user met software crash, core dump file (like as core.xxxx) will be generated
- Disable "core dump" function by using "ulimit -c 0"
Note: the developer will use "gdb -c corefile problematical-executable", "bt" command in gdb to know what happened, with call stack info.
