Description soldatov 2014-11-06 09:23:25 UTC 
Scenario:
- Add remote USA host
- Call New Class wizard
- Press Finish
==> IDE creates newClass.cpp and newClass.h files, but files are empty
Comment 1 Alexander Simon 2014-11-06 10:26:40 UTC 
I have seen such behavior on fast connection.
I got randomly empty file newClass.cpp or newClass.h.
Comment 2 Vladimir Kvashin 2015-06-16 13:51:33 UTC 
Investigatiopn shows that when execution comes to this place (see the stack below), cache file is empty.
