196          by opcode, are not the correct length. It seems to be the only way to do
197          such a check at compile time, as the sizeof() operator does not work in
198          the C preprocessor. We do this while compiling pcretest, because that
199          #includes pcre_tables.c, which holds _pcre_OP_lengths. We can't do this
200          when building pcre_compile.c with PCRE_DEBUG set, because it doesn't then
201          know the size of _pcre_OP_lengths. */
