Segmentation fault (core dumped): how to diagnose and fixing?

Here the good methodologies to find and fix segmentation fault errors

  1. Compile you program using the -g -O0 gcc-switch, or add options to string CFLAGS and/or CXXFLAGS in Makefile.
  2. Then use gdb (if need - pass command argument using --args option): gdb --args ./proxmark3 /dev/ttyACM0
  3. Use some gdb magic:
