Precisely my point: they're not.  That backtrace is false data.

This one I believe to the extent of the series of function calls, but
it's still giving you wrong info about the passed parameters, which
is pretty common if you compiled at -O2 or higher.  Try recompiling with
"-O0 -g" if you need trustworthy parameter info from the backtrace.
