fcollapse fails with string by variables (Stata 14/MP)

[mcaceresb]

. sysuse auto, clear
(1978 Automobile Data)

. version 14

. fcollapse price, by(make)
      st_varvaluelabel():   181  Stata returned error
    Factor::store_keys():     -  function returned error
            f_collapse():     -  function returned error
                 <istmt>:     -  function returned error
r(181);

Interesting. On Stata 14 this works fine, so I'm guessing that one of the Mata functions changed (and that is not supported by version control AFAIK).

I also checked the code and there is nothing obviously code with this line. The only time st_varvaluelabel() is called is if st_isnumvar() is true, as per the line above.

Actually, I get another error with ftools on the server I'm running this on:

. sysuse auto
(1978 Automobile Data)

. fisid make
function is_id() not declared in class Factor
(2 lines skipped)
(error occurred while loading fisid.ado)
r(3000);

. fisid price
function is_id() not declared in class Factor
(2 lines skipped)
(error occurred while loading fisid.ado)
r(3000);

All works fine on my local machine.

Could you try running ftools, compile and then clear all?

[mcaceresb]

Same errors.

BTW, I tried on Stata/MP 15.0 (Windows) and cannot replicate it either. I don't have access to a Linux version of Stata 15, so I'll probably hold o fixing the bug until I can spot it.

I'm closing this. I tried it on a different server with Stata 15 (MP) and the issue is gone, so i reckon it specific to the machine I was using (still odd, however).
