ModelSim 6.4b crashes after SDF annotation

Description

When I run a timing simulation with an SDF file, ModelSim 6.4b crashes after SDF annotation.

Solution

If you runtiming simulation with the SDF file ModelSim sometimes issues the following warning and then crashes:

# ** Warning: (vsim-3316) No solution possible for some delayed timing check nets. 7 negative limits were zeroed. Use +ntc_warn for more info.
# Region: /test
# Attempting stack trace sig 11
