Terra,
you didn't specify how you got GDAL and PROJ, and which versions of
those you use.
Make sure to solve the "proj_create_from_database: Cannot find proj.db"
error. Check if the PROJ_LIB environment is set and if it points to the
directory where proj.db is placed
The "free(): invalid pointer" error could also suggest that you have
several PROJ versions that are linked at runtime by GDAL.

I have two TIFs that I'm able to run gdal2tiles on without issue,
however, when I do gdal_merge I am unable to do gdal2tiles on the
result. When I did gdal_merge on the two TIFs I got this warning:
Warning 1: PROJ: proj_create_from_database: Cannot find proj.db
Warning 1: The definition of projected CRS EPSG:3857 got from
GeoTIFF keys is not the same as the one from the EPSG registry,
which may cause issues during reprojection operations. Set
GTIFF_SRS_SOURCE configuration option to EPSG to use official
parameters (overriding the ones from GeoTIFF keys), or to GEOKEYS
to use custom values from GeoTIFF keys and drop the EPSG code.

Despite the warning the two TIFs merged without issue, however, when I
try to run gdal2tiles on the merged TIF I get this error:

When I do gdalinfo on the merged TIF I get this:

Any ideas?
