A bit hard to trace this down definitively (due to some curl and openSSL upgrades we did around the same time), but we might have started seeing this error after...

Hi @DennisHeimbigner - sorry to nudge you, but anything you can say so far? Any additional data we can provide? Thank you for taking a look! Kris

Thank you so much, Dennis! Any thoughts on why we might not be seeing this issue with netCDF prior to v4.7.3 (+ the older versions of curl and openSSL)?

Hi Dennis, I've attached the reproduction code in my [original post ](https://github.com/Unidata/netcdf-c/issues/3105#issue-2904985196) above (we initially saw the issue with `nc_get_vars_double` ). I have also provided [output](https://github.com/Unidata/netcdf-c/issues/3105#issuecomment-2714100913) with `CURLOPT_VERBOSE 1` above...

Thank you, @DennisHeimbigner - using `#encode=` to turn off encoding does seem to resolve the issue!

I see that in netcdf/liblib/CMakeLists.txt SZIP_FOUND is false, and that SZIP libraries are not included in TLL_LIBS. So my best guess is that these dependencies are brought in by HDF5...

Thank you for taking a look and the quick confirmation! I was looking at our timeline to see if the new dependency might be explained by when we started building...
