Hello...
realloc() may move the memory being realloated. To quote from the man page,
realloc() returns a pointer to the newly allocated memory,
which is suitably aligned for any kind of variable and may
be different from ptr...
It doesn't (and couldn't) mutate the pointer temp_c_buf directly.
Thus, you probably want to re-write your code to do
temp_c_buf = realloc(temp_c_buf, 5000 + 5000);
