Check malloc return value for NULL.
If malloc cannot allocate enough memory, it could return NULL. This is not necessarily true for default Linux settings, but can be provoked there as well by adjusting proc entries. Other systems like the *BSD ones definitely do this. The function _emalloc exists for exactly this purpose, so use it instead of calling malloc directly.
