That will turn on release-checking by default which means that tree-checking macros are omitted for dump_gimple_stmt and thus different code gets generated. You might want to check if the same issue can be reproduced on trunk with --enable-checking=release. And then dig into why dump_gimple_stmt is miscompiled w/o checking. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43740
