st: xtabond2.mata: a bug?

[Roberto <terrymondo@onetel.com>]

Dear all, I very recently passed to Stata9 and therefore I was very 
hopeful in the "speed improvements" of the new code. Unfortunately at 
my first attempt I have encountered an error. I read from the email 
of David Roodman that,  if we got a red message it would probably be a bug
this is what I receive:
xtabond2_mata():  3900  unable to allocate real <tmp>[45984,843]
                 <istmt>:     -  function returned error

I am trying to estimate the following equation following the notation 
suggested to me by the author of the routine:
 xtabond2 lev l.lev mtbv size1 mat1 collateral profitability ndts 
year1-year24, gmm(lev mtbv size1 mat1 collateral profitability ndts, 
lag (2 7) equation(diff))  gmm(lev mtbv size1 mat1 collateral 
profitability ndts, lag(2 2)) iv(year1-year24, equation(level)) 
robust  noc small twostep h(2)

this is a brief summary of the dataset I am using:

Last, I have a Pentium 4 3.2Giga with 1 Giga RAM memory.
My Stata9 is fully updated and I am using the most recent version of 
xtabond2: 2.0.0 16Nov2005

I have searched in past Statalist for possible solutions to this 
issue but I had no luck.

Is this a "bug"?. Is there a solution to this issue?

Thank you in advance for your kind attention.
Best Regards
Roberto
