--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's not only "slow", it also produces a gigantic executable, the .original
dump was 7.1GB when I stopped the compilation ...
The culprit is c_genericize calling c_genericize_control_r which must somehow
do the ubsan instrumentation as well.
