st: "type mismatch" in iterated sureg

["Huiber Gabi (nat1gxh)" <nat1gxh@ups.com>]

Hello all,

A colleague of mine is running an iterated sureg. Stata proceeds to working,
but after the twelfth iteration or so a "type mismatch" error message pops
up. We're stumped. Any help would be greatly appreciated.

Thanks,
Gabi
