kittyfault

Replace your SIGSEGV handler with a cute little kitty cat. Unofficial fork from dogfault.

Tired of seeing the vanilla Segmentation fault (core dumped) message? Simply drop kittyfault.h into your program's folder and include it. You will be met with an adorable little feline delivering the otherwise morbid news.

Usage

Load kittyfault.h as an installed library and compile with the -I. flag or -I<kittyfault-directory-path>.

To enable stack trace detection (*Nix only), programs compiled against a specific ANSI C standard must specify the POSIX standard using -D_POSIX_C_SOURCE=199309L (199309 or greater) or by compiling with --std=<gnu std version> instead of --std=<std version>.

Furthermore, to enable function name detection *Nix environments must compile with the -rdynamic flag.

Otherwise, this header is compatible with both WIN32 (MinGW, etc) and *Nix environments.

Compatible with both gcc and clang.

Example

/* example.c */
#include <kittyfault.h>

void foo();
void bar();

int main()
{
    foo();

    puts("I shouldn't be printed\n");
    return EXIT_SUCCESS;
}

void foo()
{
    bar();
    puts("I shouldn't be printed either\n");
}

void bar()
{
    const char *s = NULL;
    printf("%c\n", s[0]); // standard segfault
}

POSIX Output
