CCS 10 issue

I can repeat the crash, with the attached project created in CCS 10 using the customer's source code. The crash is intermittent, in that just selecting "Rebuild Project" in CCS sometimes works and sometimes causes a crash.

The CCS console output after a crash:

**** Clean-only build of configuration Debug for project MSP430_case_compiler_crash ****

I noticed that after a compiler crash the Windows 10 event log is reporting the following as an APPCRASH for opt430.exe:

However, the .dmp file reported in the event is no longer present so can't attach it.
