--- Comment #11 from Adrian Perl <adrian.perl at web dot de> --- Yeah, my mistake. My IDE failed to look up the function and a short search on the internet revealed only builtin_trap (https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html) You just saved me hours with the -j hint! I assumed it was not applicable as it is not used in the guide (https://gcc.gnu.org/contribute.html). Thanks
