I changed my mind on whether this bug should be fixed for 0.6.0.  Disagreement welcome.

The EXAMINE part of this bug has now been fixed.

The only existing part of this bug, is the T-TEST issue.  But T-TEST currently has a test to ensure that the independent variables are not long string variables.  This is not ideal, but at least it doesn't crash, and doesn't return incorrect data.  So I'm downgrading the severity of this bug.

The FREQUENCIES part of this bug should have been fixed in src/language/stats/frequencies.q version 1.9.

Strings more than 8 characters in length cause problems as demonstrated by the code below.  The output generated by the EXAMINE and FREQUENCIES commands display incorrectly, whilst the T-TEST command crashes.

DATA LIST LIST /n * s (a34).
100 OneHundred
222 TwoHundredAndTwentyTwo



        /GROUPS = s("OneHundred","TwoHundredAndTwentyTwo")
        /VAR = n.
