It means you have heap corruption in your program. You likely allocate some memory using malloc, but write outside the actual bounds, corrupting the heap. When you call free, glibc detects the corruption and reports it (specifically, the size of the next free chunk is overwritten). You should definitely fix this problem. Valgrind can be … Read more

The simplest way to share your program is compile it and share the binaries. There are a lot of open question you will have to solve (libraries dependencies, specific distribution configurations, …). You must to precompile for every targeted hardware architecture (x86-64, ARM, …) and for every specific SO (BSD, Linux, … even Windows). As … Read more
EDIT. Since my compiler does not have uint64_t I have shown two ways to save a 64-bit value to file, by using unsigned long long. The first example writes it in (hex) text format, the second in binary. Note that unsigned long long may be more than 64 bits on some systems. #include <stdio.h> int … Read more
