Dear Allin,
the error is still present.
What kind of other information is necessary in order to eliminate this bug?

######SCRIPT OUTPUT##################
gretl version 2016e-git
Current session: 2016-11-20 22:41

? function matrix stata_reorder (matrix se)
> # stata puts the intercept last, but gretl puts it first
> scalar n = rows(se)
> return se[n] | se[1:n-1]

? open data4-1

Read datafile /usr/local/share/gretl/data/data4-1.gdt
periodicity: 1, maxobs: 14
observations range: 1 to 14

Listing 5 variables:
  0) const     1) price     2) sqft      3) bedrms    4) baths

? ols 1 0 2 3 --cluster=bedrms --quiet
? matrix se = $stderr
Generated matrix se
? foreign language=stata --send-data
? regress price sqft bedrms, vce(cluster bedrms)
? matrix vcv = e(V)
? gretl_export vcv "vcv.mat"
? end foreign
? matrix stata_vcv = mread("vcv.mat", 1)
/home/acer/.gretl/vcv.mat: No such file or directory

Error executing script: halting

########TERMINAL OUTPUT#############
acer at acer:~$ gretl
gretl_invert_symmetric_matrix: dpotrf failed with info = 2 (n = 2)
wald_test: couldn't invert C
gretl_clipboard_get: info = 0 (TARGET_UTF8_STRING)

Sometime ago there was a discussion about implementing some kind of
automatic testing of Gretl, on Ubuntu 14.04 I can test the export/import
functions with other programs (Stata, R, Python,  Octave, Julia, not Ox).

Best regards,


Mihai
