<pre>Repro on trunk:
int *foo(unsigned long bar, bool baz) {
int *i = reinterpret_cast<int *>(bar);
if (!i)
i = new int;
if (baz)
return i;
if (!bar)
delete i;
return 0;
}
Command: $clang --analyze foo.cpp
foo.cpp:9:10: warning: Potential leak of memory pointed to by 'i'
return 0;
^
If I change the `if (!i)` to `if (!bar)`, the warning disappears.
Warning does not disappear if I use `uintptr_t` instead of `unsigned long`.
Thank you!</pre>
