I finally tracked back to your original message. I think the problem 
has to do with version control. Again, most of xtreg_fe.ado is being 
run with version set to 6. Try this code:

version 11.2
                        local my_test_local Hello world
                        noisily di      "*****************"
                        noisily di      "local my_test_local contains"
                        noisily di  "`my_test_local'"
                        noisily di      "evaluating the local 
my_test_local using macval() yields"
                        noisily di      "`macval(my_test_local)'"
                        noisily di      "*****************"
version 6
                        local my_test_local Hello world
                        noisily di      "*****************"
                        noisily di      "local my_test_local contains"
                        noisily di  "`my_test_local'"
                        noisily di      "evaluating the local 
my_test_local using macval() yields"
                        noisily di      "`macval(my_test_local)'"
                        noisily di      "*****************"

It works fine with version set to 11.2. It produces the same problem 
you got when version is set to 6. If you dug through the history of 
changes to Stata you could probably figure out why.

So, either change the version for your block of code -- and then 
reset it to version 6 -- or rewrite your code so it works right under 
version 6.
