-Ggdb'nin benim için kullandığımız başka bir hata ayıklama seçeneğinden daha iyi çalıştığı en az bir örneğim var:
amitkar@lohgad:~> cat > main.c
#include <stdio.h>
int main(int argc, char **argv)
{
printf("Args :%d\n", argc);
for ( ;argc > 0;)
printf("%s\n", argv[--argc]);
return 0;
}
amitkar@lohgad:~> gcc -gstabs+ main.c -o main
amitkar@lohgad:~> file main
main: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.6.4, dynamically linked (uses shared libs), not stripped
amitkar@lohgad:~> /usr/bin/gdb ./main

Not: Bu yalnızca x86-64 kutularında olur ve -ggdb ile derlendiğinde ortadan kalkar. Ancak hata ayıklayıcının daha yeni sürümleri -gstabs + ile bile çalışır.
