> is there sth else that I need to do to "enable" VTA? The above should be enough. But, really, it would probably be more advisable to report a problem (incompatibility between compile- and link-time options), or discard the DEBUG stmts, if -fv-t-a is not enabled at link time. Anyhow, the problem you're seeing is more likely to be the result of a lack of a NONDEBUG_INSN_P somewhere, indeed. It's odd that it doesn't hit without LTO; are you exercising significantly different code paths in RTL processing? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41230
