Thanks for the further details - in summary, as part of the changes to DBG_INSTR_REF, we started using the variadic syntax for debug values that would normally have been non-variadic - there's no fundamental problem with this, but clearly some edges weren't fully ironed out. I'll submit a patch shortly with a fix - do you have a reproducer for the issue?
