Can Uninitialized Booleans Crash a C Program?

Does the C standard allow for an uninitialized bool to crash a program?

C allows uninitialized bools, and the behavior is implementation-defined. This means that different compilers may handle uninitialized bools differently.

In this case, the compiler was allowed to assume that the bool could only have the values 0 or 1. It then used this assumption to generate code that was susceptible to crashing if the bool had any other value. This is a valid implementation, as the C standard does not specify what will happen when an uninitialized bool is used.

It is important to note that this behavior is not guaranteed across all compilers or platforms. Some compilers may generate code that is more resilient to uninitialized bools, while others may generate code that is more likely to crash.

As a general rule, it is best to avoid using uninitialized variables in any programming language. This is because uninitialized variables can lead to unexpected behavior, which can be difficult to debug.
