st: -clear matrix- interrupts -esttab-

[Michael McCulloch <mm@pinestreetfoundation.org>]

Dear Statalist members,
I'm using several propensity score models in sequence, reporting  
results in a table compiled by -esttab-.
In Stata9, I could run the do-file structure as shown below.
In Stata11, after running the code below, I receive an error message:
	. set mem 4m
	no; Stata matrices have not been cleared
	(type -clear matrix- to clear Stata matrices)
	r(4);
However, if I insert -clear matrix- prior to reloading the data in  
order to run -set mem 4m- (it's a large dataset), then -esttab- will  
only return the second model results, and drops the 1st model,  
presumably because of -clear matrix-. Is there another way to go about  
this?

****** begin code ******
set mem 4m
load mydata.dta
keep if group==1
eststo model1 stcox covarA covarB
pscore covarA covarB, pscore(pscore)

set mem 4m
load mydata.dta
keep if group==2
eststo model1 stcox covarA covarB
pscore covarA covarB, pscore(pscore)

esttab * using Table1.rtf, replace
****** end code ******
