    Details

    • Type: Bug
    • Status: Reported
    • Priority: P4: Low
    • Resolution: Unresolved
    • Affects Version/s: 5.8.0
    • Fix Version/s: None
    • Labels:
      None
    • Environment:
      Crashes on two different computers, both with Linux Mint 17.2 64-bit.
      gcc: Ubuntu 4.8.4-2ubuntu1~14.04.3
      libgtk-3-0:amd64: 3.10.8~8+qiana
      libgtk2.0-0:amd64: 2.24.23-0ubuntu1.2

      Description

      As seen in "BugTest.txt", AddressSanitizer reports a "heap-use-after-free" when this line is called:

      filename=QFileDialog::getOpenFileName(this, tr("Open"), QString(), tr("Files (.)"));

      Adding the home directory as a location suggestion makes no difference. This worked fine in Qt 5.7.0 and some versions before. I made a simple test case to show that it crashes with Debug and Release 5.8.0 and works with Debug and Release 5.7.0. It might be a GTK issue, somehow.
