Is this with a very recent snapshot? Then it could be fallout from
another fix that Allin applied in that area because of another Mac problem.
No, it's a snapshot preceding the 2020b release.
Fred, thanks for the report but can you give us some more details,
please? I can see from the crash dump that there's a buffer overflow
in print_equation_stats() in the model table code, but on a simple
test I'm not able to replicate the problem and it's not obvious how
it's coming about. It would help to know what language you have
gretl running in, what's the estimator for the models in
question (OLS, or something else?), and what aspect of the model
table format you were trying to change.
If you're able to describe a walk-through example using one of the
built-in gretl datasets that would be great.
For reference, here's the test I tried:
Open Ramanathan data4-10
Via GUI estimate 3 models with ENROLL as dependent but with varying
numbers of regressors. In each case "save as icon".
Drag the 3 models onto the model table and open it for viewing.
Change various aspects of format (column headings, significant
digits, show p-values, ...). No crash.
Tried this in both English and German.
