  1. Qt Creator
  2. QTCREATORBUG-25837

Crash on session switch (or on shutdown) after modifying and saving CMakeLists.txt

    XMLWordPrintable

    Details

    • Platform/s:
      Linux/X11

      Description

      To reproduce:
      1. Load Creator project into Creator.
      2. Modify src/plugins/diffeditor/CMakeLists.txt by inserting a space on the end and save changes (so, effectively you just "touch" the file).
      3. Close Creator. It crashed with various messages, like: "corrupted double-linked list" or "malloc_consolidate(): unaligned fastbin chunk detected". The same happens if you switch session instead of closing Creator.

      Call stack for "corrupted double-linked list":
