You are debugging a complex COBOL program, and you encounter a "segmentation fault." What does this error indicate, and what debugging steps would you take to address it?

A segmentation fault in COBOL typically indicates a memory access violation, often caused by attempting to access memory that the program doesn't have permission to access. To address this issue, debugging steps may include analyzing the program's memory usage, checking for array out-of-bounds accesses, inspecting pointer usage, and using tools like memory debuggers or runtime analysis tools to identify the source of the error.
