You can basically following in root folder: $ mkdir objdir $ cd objdir $ ../configure --enable-languages=c,c++ --disable-multilib --disable-bootstrap --disable-libsanitizer $ make -j8 $ ./gcc/xg++ -Bgcc [rest_of_options] That should trigger the ICE. > > I'm running creduce again, so I'll get back to you on that once it has > finished running. > > Thanks. > > Thanks.
