realloc potential memory leak?

Line 164 of 'cgi/html.c', there is:

parts = (struct _parts *) realloc (parts, sizeof(struct _parts) * 
part_count);

Couldn't this be a potential memory leak in case 'realloc' fails and 
returns 'NULL'? Then the reference to 'parts' will be lost, resulting 
in a memory leak.
