fatal exception
<programming, operating system> A program execution error which is
trapped by the operating system and which results in abrupt termination of the
program.
It may be possible for the program to catch some such errors, e.g. a floating
point underflow; others, such as an invalid memory access (an attempt to write
to read-only memory or an attempt to read memory outside of the program's
address space), may always cause control to pass to the operating system without
allowing the program an opportunity to handle the error. The details depend on
the language's run-time system and the operating system.
