    Description

      Hello,

      For the first time, I am testing clang code model with Qt Creator 3.6 rc1 (which seems very promising), and often I am not able to save a particular header file (.h). I have then the error message "not possible to save ..." ending by "Disk full ?". Each time I have the error, Qt Creator creates a backup of the header with a name having a number at the end ("XXX.h.F551256" for example).

      When I look to the processes having a handle blocking the file, sometime there is only the qtcreator process, sometime there is the qtcreator and the clangBackend processes.

      I then delete the handle(s) (with process sysinternals) and I can save the file.

      This occurs only on header file, not on source file (.cpp).
