One thing to test, is to delete the db and incremental_db directories in the synthesis directory. This will cause a full recompile of all modules, and I have seen it fix issues like this in the past. It's probably caused by a corrupt db file.
If that doesn't work, you'll need to open a support case, and they will require your project files to reproduce it.
If you can isolate the code that causes this issue, build a small test case and submit it with your support case.
