Hi
bereid, I've to say that I didn't experience this kind of trouble with v12 at least.
As far as I can see v12 is considered as 'one of the best releases ever'... and that's also my opinion
However, I think a possible reason why nobody replied to your problem report could be that you didn't post any detailed information (especially the example cpp/h files you've prepared).
Hence nobody could do a cross-check to confirm the problem/give some advise/provide a solution.
What about posting the simple example you've prepared and the information about the compiler config. you're using ?
If there is some advanced preprocessing involved your 'usercpp.h' file would be also useful.
