So with the optimization it at least should not print

(gdb) print *p[1]
Cannot access memory at address 0x0

but instead

(gdb) print *p[1]
<optimized out>

not sure if that is a gdb bug though ('p' is optimized out - does the
debug info say that 'p' is zero?).  Jan, can you investigate that at
the gdb side?
