Thank you for stating the versions!

There is some disagreement about sizeof() some type or struct.
Which compiler and version was used to build callgrind and callgrind_control?

What is the CPU hardware architecture of the host (where callgrind_control
is running: "$ uname -m -p -i") and the target (the execution being
measured: "$ file ./my_app")?
