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?
