I have a reproducible crash (on gretl 1.8.6, but don't know if the cause
was recently introduced or not).
It happens when you call the main function in the attached function
package with the same series in the first and second arguments (target
and cause), like so:
# in the context of denmark.gdt
matrix check = BreitungCandelonTest(LRM,LRM,null,3,100,0.05)
This is of course rubbish, but gretl shouldn't crash. (not a freeze, but
I will update the function package to check for such bad input and then
upload the new version to the server. So for testing use the package
attached to this email, not the one that will soon be on the server.
