osgearth_conv command that worked in 3.5 failing with segfault on tip

[michaelgtodd]

Describe the bug An osgearth_conv command that worked in 3.5 now produces a segfault on the latest.

To Reproduce Steps to reproduce the behavior:

1. Install osgearth
2. Run the below command (with a valid token):

   osgearth_conv --in driver arcgisserverelevation \
             --in url https://services.arcgisonline.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer \
             --in token <token omitted!!> \
             --out driver tmselevation \
             --out url output_geo/tms.xml \
             --out format tif \
             --min-level 10 \
             --max-level 10 \
             --extents -90 -180 90 180 \
             --profile global-geodetic \
             --no-overwrite \
             --threads 8

Expected behavior osgearth_conv begins downloading tiles

Michael, are you saying it doesn't work with a token but does without? Or neither work for you?

Thank you

Also around that time, there was segfault on RH that was later fixed. Have you tried grabbing the latest master?
