The core file is normally called core and is located in the current working directory of the process. You should then be able to analyze the specific failure instead of trying and failing to reproduce bugs. You can both be happy since gdb will load any core dump as long as you have a exact copy of your executable: gdb path/to/binary my/core.dump. Yeah, but I'd like me to be happy instead of gdb so it basically contains everything that gdb needs (in addition to the executable that caused the fault) to analyze the fault. Pointer, memory management information, and other processor and Processor registers, which may include the program counter and stack Program state are usually dumped at the same time, including the consists of the recorded state of the working memory of a computer Now what it contains is system specific, but according to the all knowing encyclopedia: You may want to write your own handler or use the current directory. (See Core dumped, but core file is not in the current directory? on StackOverflow)Īccording to the source this is handled by the abrt program (that's Automatic Bug Reporting Tool, not abort), but on my Arch Linux it is handled by systemd. Written to the standard input of that program instead of to a file. The rest of the pattern as a command to run.
