# Intersection algorithm between two infinite cylinders is hanging

# Attention!!!
# The test on performance meter.
# On the MASTER it takes:
# Elapsed time: 0 Hours 0 Minutes 6.3723911111 Seconds
# CPU user time: 6.15625 seconds
# CPU system time: 0.0625 seconds

# The intersection curve is almost infinite.
# Therefore, we must have failed to return
# any section curve (see comments to the issue #26894).
