SIGSEGV is abbreviation for “Segmentation Violation”.įew cases where SIGSEGV signal generated are as follows, Segmentation fault(SIGSEGV) and Bus error(SIGBUS) are signals generated when serious program error is detected by the operating system and there is no way the program could continue to execute because of these errors.ġ) Segmentation Fault (also known as SIGSEGV and is usually signal 11) occur when the program tries to write/read outside the memory allocated for it or when writing memory which can only be read.In other words when the program tries to access the memory to which it doesn’t have access to.
