These formats are generally more difficult to analyze than regular files, but can still have very helpful information for solving the bug causing the crash. [6] Example of an internal compiler error: somefile.c:1001: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
For #include guards to work properly, each guard must test and conditionally set a different preprocessor macro. Therefore, a project using #include guards must work out a coherent naming scheme for its include guards, and make sure its scheme doesn't conflict with that of any third-party headers it uses, or with the names of any globally visible macros.

But the preprocessor includes a file regardless of the extension. In fact, sometimes code includes .c or .cpp files. To prevent including the same file multiple times which often leads to a compiler error, a header file typically contains an include guard or if supported by the preprocessor #pragma once to prevent multiple inclusion.
assert.h is a header file in the C standard library. It defines the C preprocessor macro assert and implements runtime assertion in C. assert.h is defined in ANSI C as part of the C standard library. In the C++ programming language, assert.h and < cassert > are available; both are functionally equivalent. [1]
In C and C++, a header file is a source code file that allows programmers to separate elements of a codebase – often into reusable, logically-related groupings. A header file declares programming elements such as functions, classes, variables, and preprocessor macros. A header file allows the programmer to use programming elements in multiple ...

Writing to read-only memory raises a segmentation fault. At the level of code errors, this occurs when the program writes to part of its own code segment or the read-only portion of the data segment , as these are loaded by the OS into read-only memory.
