--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> --- There's very similar one seen by Jakub in: https://gcc.gnu.org/ml/gcc-patches/2016-12/msg01765.html $ ./xgcc -B. -fsanitize=nul /tmp/a.c xgcc: error: unrecognized argument to -fsanitize= option: ‘nul’ $ ./xgcc -B. -fsanitiz=nul /tmp/a.c xgcc: error: unrecognized command line option ‘-fsanitiz=nul’; did you mean ‘-fsanitize=null’?
