My project is for a 5510.  I'm on CCSv4_1_3, using CGT 4.3.6 and BIOS 5.41.04.18

 

Randomly, when building my project, I'll get TONS of these errors... ex ://

Let me stress that these aren't real errors.  All I did was move one line of code and build.  This happens frequently, and it's impossible to get the app to build again until I reboot my machine!  After rebooting my machine, it builds normally, as it did before.  But restarting CCS doesn't fix it.  Changing workspaces doesn't fix it.  The only thing I've found to fix this issue is a reboot. (Annoying)

Some things cause it quite consistently.  I've found that if I change the optimization settings in my builds, it's virtually 100% guaranteed that this will happen.  (i.e. -o1 to -o3)  However, this time it happened when I commented out an "if" statement and hit build.

Does anyone know why this happens?  It's a huge time-waster for me.

    Would it be possible to provide a reproducible test case?

    Well, I don't think I can send my project off since our company doesn't like that type of thing.  But I can reproduce it pretty readily... like within a matter of an hour or so of building and rebuilding during my normal work flow.  If you'd be willing to tell me what you're looking for, I could try to watch for it when this happens again.

    Would it be possible to strip down the project so that there is nothing confidential? It can be a dummy project... so long as the error can be reproduced.
