Fixing 'Segmentation Fault (Core Dumped)' in Multi-OS Applications

The 'Segmentation Fault (Core Dumped)' error occurs when a program attempts to access memory it is not authorized to use, leading to a crash.

This error is common in low-level languages like C and C++ but can also occur in applications interfacing with these languages on different operating systems.

Causes include dereferencing null or uninitialized pointers, buffer overflows, and invalid memory accesses.

To resolve this, start by enabling core dumps with commands like ulimit -c unlimited on Linux or configuring Windows Debugging Tools.

Analyze the core dump using tools like gdb (GNU Debugger) to trace the faulty code.

Enable compiler warnings with flags like -Wall and consider using memory debugging tools such as Valgrind or AddressSanitizer.

Writing thorough unit tests, reviewing pointer operations, and adopting best practices in memory management can significantly reduce the likelihood of segmentation faults.

For applications running across OSs, ensure thorough compatibility testing to catch potential issues early.
