If you migrate older designs into Quartus you may
get some internal
errors and the program may crash.  I had dug into this some time ago to
find the root cause of the crash and spoke with Altera who confirmed
the problem.  I just installed the most current version of Quartus and
the problem is still there.

So, if you run into this, look in the .QSF file and see if the
following line is included:

set_global_assignment -name TDO_DUMP_FILE AUTO

If there is, remove it and try to build.  I am not sure what versions
of the Altera tools added this command, but starting with Quartus 5, it
will crash the program.  

Hope this saves someone some time ......
