Generate a 0-byte core file. GDB cannot identify the core file.

(GDB) Core-file core.300
"/Mnt/HGFS/D/fsvspsvn/src/PF/core.300" is not a core dump: file format not recognized

 

Problem:

We are runningProgramWe often encounter segment errors without segment fault. In this case, we need to use GDB and then use core-file to analyze the generated core. *** file.

However, it is strange today that the size of all core. *** in production is 0 bytes.

 

[Root @ qljt pf] # ulimit-C
Unlimited

 

Therefore, it should not be a ulimited problem.

 

Problem:

I ran the program (generate core. * ** program) is not in the Linux directory, but under a partition in Windows (this partition is shared by vmtool "/mnt/HGFS/***" and Linux ),

The generated core. *** is 0 bytes in size.

 

Solution:

Copy the program to be run to the linux root directory and run the generated core.
