In computing, a bus error is a fault raised by hardware, notifying an operating system (OS) that a process is trying to access memory that the CPU cannot physically address: an invalid address for the address bus, hence the name. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions. WebMar 5, 2024 · Segmentation faults in C/C++ occur when a program attempts to access a memory location it does not have permission to access. Generally, this occurs when memory access is violated and is a type of general protection fault.

"WebUnfortunately, malloc () is required to return word-aligned allocations, since many CPUs can only access a word when its address is aligned. The conflict happens when software makes a memory allocation using a size that is not a multiple of the word size, and expects to do word accesses to that allocation. " - Malloc sigbus
