Hi,
the reason is -msse3 that is supposed to be at both invocations.  -msse3
enables the SSE builtins that do change declarations UIDs that in turn changes
function names:
< ;; Function ddx (ddx.1401)
---
> ;; Function ddx (ddx.1390)
so profiles can't match.  While it is possible to ignore the SSA names, I don't
think there is actual need to mess with this - the use of different swtiches
that do affect input language clearly can't be much accepted in between train
and compilation run
(I am hoping that optimization switches like -funroll-loops will run, but for
language features, like SSE is we will get different divergences anyway)

The other problem was fixed, so I am closing the PR.
Honza
