--- Comment #3 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to 庞庆源 from comment #2) > gcc pmalloc.c -O2 -o ppp -ldl -fno-tree-loop-distribute-patterns > -fno-strict-aliasing > Still not work. -fno-builtin (the malloc+memset -> calloc is not part of loop distribution) > Why I don't see stack overflow if this will trigger function loop calling tail call?
