I am hunting for an uninitialized memory issue. I have integrated
valgrind into my code, using cmake find_package, but when I call
|VALGRIND_CHECK_MEM_IS_DEFINED| it always returns 0 no matter what I
pass in. For example |VALGRIND_CHECK_MEM_IS_DEFINED(0x00,0xFFFFFF)|
returns zero.
Am I missing something ?
Well address zero is likely uninitialised so you would expect it to
return zero as that is the address of the first uninitialised byte in
the block - obviously that is unhelpful because it's the same response
as if the whole block was defined but real systems will never use
address zero for anything.
