QUESTION
i have a project that works well on ubuntu after compiling, the snippet is like:
...ANSWER
Answered 2017-Nov-07 at 15:37It would be interesting to print the value of jj
just after get cash
.
My crystal ball says that it would have a very large positive or negative value, in which case your problem is stack buffer overflow somewhere in newBar
, or one of the functions it calls.
Building your program with Address Sanitzer (g++ -fsanitize=address ...
) should point you straight at the problem.
Update:
i print the value of jj just after get cash but it says its still 3
You have to realize that
- there is no magic (either
jj
is not really 3, or your compiler is broken (very unlikely)) - debugging is a skill
What is possibly happening is that GDB prints only the lower 32 bits of jj
, but the compiler uses entire 64-bit register (assuming 64-bit machine) to perform the comparison (and expects the high bits to all be 0). And something in newBar
sets the high bits of jj
to non-zero value.
Now, you can debug this in one of several ways:
- use
disas
command, find the actualcmp
instruction, examine registers at time of comparison, or - change the type of
jj
fromint
tosize_t
(at least GDB will then not perform any truncation), or - run under Address Sanitizer (as already suggested).
