Use the map and COD files to find the crashed code line

// The map and COD files are generated at the end

 

Run debugProgramThe error message is as follows:

1. The error address is 0x00413202.

 

Search 00413 in the map file:

 

 

2. Find the largest 0x4131e0 value smaller than 0x00413202, and the function name is crashtest.

 

3. the offset of the crash address to the function address is 0x00413202-0x41_e0 = 0x22.

 

Find the crashtest function in the cod file where the function is located:

 

 

4. Check the row 0x22.

 

 

5. You can see error statements or even error operations.

 

----------------------------------------

To generate map and COD files, you must modify the debugging project settings. Take vs2008 as an example:

1. Set linker-debugging-generate map file to yes.

 

2. Set C/C ++-output files-assembler output to assembly, machine code and source (/FACS)

 

Note: The cod file is in the temporary compilation folder, along with the OBJ file.
