--- Comment #46 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-02-22 13:09:10 UTC --- (In reply to comment #43) > 400.perlbench fails with a global-buffer-overflow which clang does not detect. > I did not investigate why. It could be a gcc false positive or clang false > negative. On which file/function the global-buffer-overflow was? Can you send me the asan diagnostics? > 464.h264ref is VERY slow, I did not look why. And it didn't fail on that: for (dd=d[k=0]; k<16; dd=d[++k]) { satd += (dd < 0 ? -dd : dd); } or have you fixed that up in your SPEC sources?
