The most likely reason is that the data you get from malloc is not initialized to any particular value. If your program does not set some of that data before you use it, then you will have unpredictable results. Either change your program to always set sensible values, or use memset to set a particular value, or use calloc instead of malloc to allocate pre-initialized memory.
