Massive memory "leak" in QtCreator

    Description

      I saw a massive memory consumption/leak in QtCreator when loading big projects (e.g. Qt Creator itself)

      Steps to reproduce:

      • Clone QtCreator's srcs
      • Open QtCreator's .pro/.qbs or CMakeLists.txt 
      • Wait until it's done parsing the project
      • Check how much memory qtcreator is using (on my side is using ~800 MB)
      • touch src/plugins/plugins.pro/.qbs/CMakeLists.txt file
      • Wait until it's done parsing the project
      • check again how much memory qtcreator is using. On my side it adds +250MB every time is reparsing the project and the cpp files.

      Also closing the project (right click -> close project) s not freeing the memory.

          Bug - A problem which impairs or prevents the functions of the product. QTCREATORBUG-23861 Qt Creator began to crash very often

          • P1: Critical - Urgent and Important, will STOP the release if matched with set FixVersion field. This includes regressions from the last version that are not edge cases; Data loss; Build issues; All but the most unlikely crashes/lockups/hanging; Serious usability issues and embarrassing bugs & Bugs critical to a deliverable. This is the highest possible priority for requirements.
