Hi Andreas,
with your macro you will change nothing. Just example:
a = gw_malloc(10)
some_func(a)
/* but here a points to some plase in memory but is not NULL */
void some_func(void *a)
{
do something with a;
gw_malloc(a);
/* ok a here is NULL */
}

I would suggest the use of a macro of the following style instead:
#define gw_free(ptr) { if(ptr) gw_native_free(ptr);ptr=NULL; }

IMHO, this feels bad.
If the programmatic logic is correct, then the freed memory cannot
be accessed
after it is free.

Hi Stipe,
your last commit:

void gw_native_free(void *ptr)

free(ptr);
+ ptr = NULL;
}
is bogus and unneeded because you just set ptr to NULL but not
pointer af
caller. So this commit does nothing to prevent situation you
described and
should be reverted.
