The status 125 means "cannot be tested" (due to unrelated build failure or 
similar).  If you have a script that produces a meaningful exit code, then of 
course you don't want it.  It might be good to have the reproducer exit with 
some value other than EXIT_FAILURE==1 and have the script do something like

src/emacs -Q -l ../reproduce.el
if [ $? -eq 1 ]; then exit 125; else exit $?; done

so that other Emacs failures do register as "skip".
