Usage

• Compile by running ./compile
• Result .so file is in lib folder
• Add LD_PRELOAD and run executable: LD_PRELOAD=<path to build folder>/gdb_on_seg.so executable
• Or export LD_PRELOAD=<path to build folder>/gdb_on_seg.so and then run the executable normally
• When a segfault, etc. occurs the program will go on hold an gdb is run and prints out the stack traces of all threads
