Currently there are several parts not checking NULL

So I fill in code checking NULL and
use zfree() instead of free().

can't see directly reasons for zfree usage,
but it looks reasonable.. do you have any
crash reports due to missing zfree?

No, Just I read source code util/parse-events.c
And I found several insufficiency, shortcoming
not checking NULL or assigning NULL value to a pointer
variable after free().
So, I think we can use zfree() insteadof free()+assigning NULL.

Change commit message to be more appropriate ?
