The code I am playing with generated by DStep involves lots of lots of structs with mixin bitfields. All of them seem to compile file, except one. How is it that:
mixin(bitfields!(
ubyte, "current_next", 1,
ubyte, "version", 5,
ubyte, "one2", 2)); /* TS ID */
can result in the following error. The line for "version" is 141 and
the one for "one2" is 142.
