>Description:
When the attached program is run, the two output lines are different, when they should be the same. e.g.:
lhs=0x22ff6c, rhs=0x22ff68
lhs=0x22ff68, rhs=0x22ff70
This translates into serious bugs, as variables are read incorrectly and random memory is accessed and updated.

Compile and run the attached program
