st: Stata appears to be eating some string IDs when saving a file

I am having a strange problem with Stata deleting the values for about 80%
of my data when I save a file. It only does it for string variables,
and this only happens some of the time that I run this code.
Here's the relevant part:
. des ;
Contains data
obs: 10,766,127
vars: 4
size: 387,580,572

byr_id str10 %10s
item_id str12 %12s
pt_m2m_cat float %21.0g pt_m2m_cat

. save "pt_m2m_cat.dta", replace;
file pt_m2m_cat.dta saved

. assert !missing(slr_id) & !missing(byr_id) & !missing(item_id) &
!missing(pt_m2m_cat);

assertion is false

My Stata MP is 12.1 (March 20, 2013), on an Ubuntu box. Any ideas how
to diagnose this?
