Encountered this while reprojecting a shapefile with the following SRS:

PROJCS["NAD_1983_HARN_StatePlane_Michigan_South_FIPS_2113_Feet_Intl",
    GEOGCS["GCS_North_American_1983_HARN",
        DATUM["NAD83_High_Accuracy_Reference_Network",
            SPHEROID["GRS_1980",6378137.0,298.257222101]],
        PRIMEM["Greenwich",0.0],
        UNIT["Degree",0.0174532925199433]],
    PROJECTION["Lambert_Conformal_Conic_2SP"],
    PARAMETER["False_Easting",13123359.58005249],
    PARAMETER["False_Northing",0.0],
    PARAMETER["Central_Meridian",-84.36666666666666],
    PARAMETER["Standard_Parallel_1",42.1],
    PARAMETER["Standard_Parallel_2",43.66666666666666],
    PARAMETER["Latitude_Of_Origin",41.5],
    UNIT["Foot",0.3048]]

using ogr2ogr yields the same error: 

ogr2ogr -t_srs epsg:3857 -f "ESRI Shapefile" ~/tmp/tolerance-condition-error.projected ~/tmp/tolerance-condition-error/finalhomicide.shp
ERROR 1: tolerance condition error

message is coming from proj4

tmcw commented 9 years ago

proj4 triggers this error from a whole lot of places. projects.h shortcuts the errorcode with a macro:

#define F_ERROR { pj_ctx_set_errno( P->ctx, -20); return(xy); }

And then triggers it from all kinds of forward-projection Mercator code.
