Although gdb works with many languages (12 at the time of writing), we’ll use C as a base for our examples. In particular, we’ll work with the C source target.c: 01 int inc(int a) { 02 return a+1; 03 } 04 05 int main(int argc, char** argv) { 06 for(int i=1; i ...

Using gdb gdbcan be quite useful for looking at the system internals. Proficient use of the debugger at this level requires some confidence withgdbcommands, some understanding of assembly code for the target platform, and the ability to match source code and optimized assembly. ...

For more information on using GDB, please see their online documentationhere. ASAN (Linux/Mac/BSD/Android)¶ AddressSanitizer (ASAN) is a very fast memory error detector and an indispensable tool for finding issues with improper memory handling such as use-after-free, buffer overflows and gener...
It is the first step that you must complete before you start using GDB to debug your code. Please compile the code using the GDB options as given in the below example. $ gcc -ggdb -Wall -o gdbtest gdbtest.c # -g: This option adds debugging info in the operating system's native fo...
