When using a bitwise OR operation on a bool reference and compiling with optimizations that include /Og (global optimizations), the resulting executable may generate an access violation.
The current implementation of a bool is an 8-bit value. The OR operation with /Og on a bool reference operates on a 32-bit value.
Do not use bitwise operators with bool references. Use bool values instead.
