Actually, in both cases, the OP is malloc'ing way too many bytes. Any
amount is too many, you see. The OP immediately loses the pointer he just got
from malloc by replacing it with the value in the host_uname->sysname pointer.
He should either use strcpy(), or not bother allocating a second buffer at
all.

#ifdef PEDANTIC
NUL bytes terminate a string.
NULL pointers point to nothing.
