Hi all,

The latest update of Stata 11 seems to have broken -fmm- . Although I haven't checked, it seems to me that the "problem" will arise for any user written likelihood. Note that this code worked just fine even two weeks ago, running without any overall version control in the do file. Now it won't run even with version control.

I'd appreciate any ideas / hints.

Best.
