Fire up gdb on the core dump (or run it under gdb until you get the fault) and find the line that the segmentation fault is happening on. Find the pointer that causes the error. Then all you have to do is to work out why it isn’t a valid pointer.

07.02.2022 · Core Dump/Segmentation fault is a specific kind of error caused by accessing memory that “does not belong to you.” When a piece of code tries to do read and write operation in a read only location in memory or freed block of memory, it is known as core dump. It is an error indicating memory corruption. Common segmentation fault scenarios:
