  I found this in HACKING:

   Please note that NULL check for the g_malloc result is redundant and
   that g_malloc() call with zero size is not allowed.

So we have:

1. You should not request 0 bytes from g_malloc().
2. g_malloc() does not return NULL (if you follow rule #1).

There is no need to check for NULL return.


Maybe there is insufficient memory, the return is error,
Do we need to check the return ?

Thank you very much for your feedback!
