[OSM-dev] osmconvert bounding polygon

Hello,

I have encountered a bug with osmconvert (version 0.8.7) with regards to
cutting out a polygon (a .poly file) from map data.
After running the command there are small bits of map data outside of the
bounding polygon that are not removed and I was wondering if anyone has
seen this behaviour before.
Here a sample of the command I am running:
osmconvert \
        --verbose \
        --drop-author \
        --drop-version \
        --complex-ways \
        --complete-ways \
        --out-o5m \
        -B=sample_polygon_file.poly \
        -o=output_file.o5m \
        input_file.pbf

Also, I am able to successfully cut out the polygon file using an osmosis
command but it is MUCH slower so I was hoping to get the osmconvert command
to work.
Sample command:
osmosis \
        -verbose \
        --read-pbf-fast file="input_file.pbf" workers=4 \
        --bounding-polygon file=sample_polygon_file.poly completeWays=yes \
        --write-pbf file=output_file.pbf omitmetadata=true

Thanks,
Brad
