Great! An update package is to be uploaded in a couple of hours. I can't find a g++ bugreport about this, do you mind filing one? Note that the actual C++ source that is (mis)compiled by g++ is a result of pre-processing of src/dsql/parse.y by an yacc preprocessor (built locally). Since the parser module is used everywhere, I'll try to disable the optimization only on freebsd-amd64 for the next upload. Many thanks for your help, Petr and Modestas!
