Typical errors that result in application crashes include:
- attempting to read or write memory that is not allocated for reading or writing by that application (segmentation fault) or x86 specific (general protection fault)
- attempting to execute privileged or invalid instructions
- attempting to perform I/O operations on hardware devices to which it does not have permission to access
- passing invalid arguments to system calls
- attempting to access other system resources to which the application does not have permission to access
- attempting to execute machine instructions with bad arguments (depending on CPU architecture): divide by zero, operations on denorms or NaN values, memory access to unaligned addresses, etc.
