Abstract
A system that automatically detects logical errors when compiling a program. The system detects such logical errors as a signal handler routine modifying the errno global variable, a signal handler routine calling a non-reentrant library function, a signal handler routine calling a non-reentrant user function, and a signal handler routine calling a memory allocation function without first disabling all other signal handlers. The system also detects using '/n' at the end of a string.
