sigsegv目录sigsegvsigsegvA SIGSEGV (Segmentation Fault) is a type of error that occurs in computer programming when a program tries to access a memory location that it is not allowed to access. This can happen when a program accesses an uninitialized pointer, accesses memory that has already been freed, or tries to write to a read-only memory location.When a SIGSEGV occurs, the operating system interrupts the program's execution and terminates it, displaying an error message to the user. This error typically indicates a bug in the program's code and can be challenging to debug.It is important for programmers to handle memory properly to avoid SIGSEGV errors. This includes initializing pointers before using them, freeing memory only once, and ensuring that memory accesses are within the allocated boundaries.
