Is this non-compliant behavior also TRUE for MySQL 5.5?

I tried 5.1.45 and still has issues.
A basic method for crossing two lines did not return the correct value
SELECT crosses(GeomFromText('LINESTRING(0 0, 10 10)'), GeomFromText('LINESTRING(0 10, 10 0)') );

This returns 0 instead of 1.

Some other functions have various issues.
