hi,

my apologies for the incomplete post. yes p will not be NULL
but have a value, but that's not the prob.

the code in question is

p = &root->child;
for (;;) {
>>	tmp = *p; <<
	if (!tmp || tmp->start > end) {
...
...

the line "tmp = *p" essentially translates to "tmp = *&root->child"
or "tmp = root->child"....so i think tmp will have a NULL val.

then won't the "if" condition where tmp's member is being accessed
"tmp->start" give a prob. (null pointer derefernce)???
