I don't see what the bug is here - this is a feature of the C++ standard,
we can't really "optimize" anything here. 5.2.9/8 ... The null pointer
value is converted to the null pointer value of

The reasoning of GCC goes as follows. There is a partial redundancy
along the two invocations of get(), as c[i] is possibly clobbered by f().
