Various Problems With Latest PSPP Version, For Alan

I just opened the data file that I generated on the previous month on the earlier PSPP version and ran the Descriptive, and got the same erroneous data on it, not the correct data I had last month on the earlier version of PSPP.  So, I have no doubt that the problem is with the descriptive on the latest PSPP version that has the problem.

I tried to attach that previous month file to this email, but it is too large to go through.  

I went to the PSPP website to get an earlier version of it, but only the latest version is set up to be downloaded.  Unfortunately, I had deleted that earlier version from my computer and I cannot find its version number.  Can you send me a version that is about 2 years old?

Sorry to hear you're having such problems. This looks like a serious
error and you should file a bug. I don't know if your dataset is
publicly available, but ideally you would include the dataset and the
PSPP syntax that generated the error. If the developers cannot replicate
your bug, then they cannot see what's wrong nor test their fixes.

If I had to guess, and it's just a guess, the size of your dataset may
be part of the issue.

Does that C++ assertion error happen every time? I wouldn't ignore it.
An assertion is code added to the program in an impossible place.
Ignoring it seems like it would lead to random results, which is what
you see.

Also, dumb question maybe, but does this happen always right after a
fresh reboot?

Although it's always good advice to use the latest version, if you
experience new bugs (as you seem to be), then it's a common practice to
go back to a previous version that worked better.

In your case, I might also be tempted to calculate some of these
descriptive statistics using simpler tools like a spreadsheet so you
have a better idea what the reality of your dataset is.
