in reply to Using bisect.pl for a thread error

You're setting -Duseithreads in the wrong place. This is Configure's -D, not the C compiler's -D. Just drop the 'Accflags':

../perl/Porting/bisect.pl -Duseithreads --start v5.14.0 --end v5.16.0 +--expect-fail -- ./perl -Ilib -e "use threads;use POE::Kernel; thread +s->create(sub{})->join; exit;"
