Hi Paul,

Thanks.
I found the relevant references now, in [1]. The fact that some people see it
not
as a property of the malloc() function but as a GCC bug [2] indicates that it
should
also apply when alloca() is used to allocate the memory. (In this case, a
program
would not crash when it makes out-of-bounds accesses on the stack, but valgrind
may still report accesses to uninitialized memory.)
