A fatal error is a critical software malfunction that instantly stops program execution and severely disrupts normal operations. Unlike minor bugs or glitches, it cannot be overlooked or bypassed.
This flaw usually leads to an unanticipated program shutdown. Prompt intervention is needed to resolve the underlying cause.
Examples of Fatal Error
- Memory overflow error: It occurs when a program attempts to utilize more memory than the system can offer. This is mainly seen in programs that manage massive quantities of data and lead to the application’s sudden termination.
- Divide by zero error: In computing activities, dividing a number by zero leads to an indefinite result. When a program accidentally tries this process, the system instantly halts.
- Null pointer dereferences: This occurs when software attempts to access a memory location via an uninitialized pointer. This causes the program to crash while fetching non-existent data.
- Stack overflow: This flaw happens when the stack, a distinct region of computer memory, surpasses its capacity because of extremely repetitive data pushes or calls. The overflow may lead to unexpected program termination.
- Misplaced system file: A program may crash if it depends on an external system library or file and fails to locate it. This may occur because of inaccurate installation, corrupted files, or accidental erasure.
