"Disk full" error message when saving file when using Clang Code Model

When using Clang Code Model plugin (static analyzer) I get sometimes the "disk full, unable to save file" error message when trying to save a file. Sometimes saving another file and then saving the original file helps but sometimes I have to restart the Qt Creator. The plugin (or Qt Creator) also generates quite a few temporary files for the file on which the error occurs and they do not get cleaned up (I have to delete them manually).
