Without any information about the source code, I don't see how we can
tell whether having the same parameters is correct behaviour or not.

That said, it is certainly possible that the arguments of the inlined
function are not being displayed correctly.  Mainline gcc has gotten
quite a bit better about debug info for inlined functions and in general
for avoiding incorrect display of variables in optimized code.
