Say you like to place a breakpoint at line 11 and step through the execution, printing the values of the local variables - the following commands sequences will help you do this: How to use the GDB (Gnu Debugger) and OpenOCD for microcontroller ....

Then use ls -ltr command in the directory to find the latest generated corefile.
To load the corefile use gdb binary path of corefile debugging - How do I debug an MPI program? I do some MPI-related debugging with log traces, but you can also run gdb if you're using mpich2: MPICH2 and gdb. This technique is a good practice in general when you're dealing with a process that's tricky to launch from a debugger. This perspective suggests that, can I use GDB to debug a running process?
Use the attach command. Check out this link for more information. Moreover, typing help attach at a GDB console gives the following: (gdb) help attach Attach to a process or file outside of GDB.
This command attaches to another target, of the same type as your last " target " command (" info files " will show your target stack). The command may take as argument a process id, a process name (with an ... How do I analyze a program's core dump file with GDB when it has .... 226 My program operates like this: exe -p param1 -i param2 -o param3 It crashed and generated a core dump file, core.pid.
Furthermore, i want to analyze the core dump file by gdb ./exe -p param1 -i param2 -o param3 core.pid But GDB recognizes the parameters of the EXE file as GDB's input. How do I analyze a core dump file in this situation? Determine the line of code that causes a segmentation fault?. According to the documentation these checks include catching segmentation faults by default.
It's important to note that, the advantage here is that you get a stack trace similar to gdb's output, but without running the program inside a debugger. Debugging: stepping through Python script using gdb?. The test_gdb.py script also gives the pointer that you can "... run "python -c'id (DATA)'" under gdb with a breakpoint on builtin_id "; for testing this, I have posted a bash script, gdb_py_so_test.sh, which creates an executable with a counting thread function, and both plain distutils and swig modules (in both debug and release versions) that ... Using GDB without debugging symbols on x86?
How do I use GDB to debug a program which do not have debugging symbols on a 32-bit x86 processor?
