Stonie, the gemlib/im code did have a problem with the zlib nids files when the data was not FILE'd with the -overwrite option from the LDM, and for some reason, a radar image was appended to with another image (reportedly LZK and FWS are seen more than once for the same time and files got appended). I have fixed that. A completely different problem with level2 radar files is finding an occasion when 2 scans have the same minute time (but different seconds, and volume numbers....seems to s a short sector scan followed in the same minute by a full scan) where the LDM pattern/action based on file output names appends to the same file. Anyhow, with gdradar, I don't know exactly where your double free is occurring, but have been working on some cleanup that solved several problems users were having, so will pount on linux hard for the 10.3 release.
