The problem is not limited to -xi- of -ice-. For example the
following code stops with a r(920) error when the length of local test
reaches 165198.
local test
forvalues i=1/166000 {
local test "`test' `i'"
local ctest : length local test
di "`ctest'"
}
...
165180
165186
165192
165198
too many macros
r(920);
