let me know if you need any locals. this is 100% reproducable.

I don't see this, and it makes no sense.  Biesi, are you sure you have clobbered
all generated files since updating sources?  Makefile.ref has no header
dependency gathering automation, and only a few hardwired deps.  You must clean
after struct size or member changes.

oh, sorry. I didn't know I had to do clobber builds with Makefile.ref. doing
that fixes this problem.
