(In reply to Guy Harris from comment #5)
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x0008
which means null pointer dereference
Please note the address is 0x0008 (eight) -- so NOT a null
pointer deref?
Sorry if this is B/S, I haven't programmed in C since 20 years... :-)
struct foo {
char *p;
char *q;
};
...
struct foo *r = NULL;
...
if (r-q == NULL)
printf(It's null\n);
is dereferencing a null pointer, but, on an LP64 or LLP64 platform with the
page at address 0 mapped out (and with a null pointer having all its bits
clear, which isn't a requirement of C or C++), it will crash trying to fetch a
pointer at an address of 0x0008.
