[Gretl-devel] invalid compressed data

Dear all, I am currently working with a 2.8GB csv data file which I stored as a gdtb file (compressed to about 170MB). However, trying to open the gdtb file yields an error (see attached screenshot) with the message that the data is not compressed in a valid manner. Smaller gdtb files work fine though. If I remember correctly, I also obtained a message refering to some 4GB limit this afternoon -- however I cannot replicate this. The issue occurs on Ubuntu 18.04 using latest git. Best, Artur
