Hi mhsec,
Thanks for reporting this problem. Unfortunately your proposed patch
will not work as it will prevent the tools from handling 64-bit binaries
with very large section sizes.
Instead I have checked in an alternative patch which checks for integer
overflow before attempting to allocate any memory, which prevents the
heap corruption from happening.
Cheers
Nick
