Hi Cyril,

before getting into the diff of the binary given we can use objdump (I
understand it only now sorry) I suggest we compare function sizes with
objdump -t.

Also I'm assuming we are 100% sure the culprint is thread.o, given the
bug looks not very reproducible I'd repeat the test a couple of times to
be super sure we have identified the culprint.

Thanks for your time and patience

  Andrea
