Title:
  Qt app crashed after upgrading Qt5 libraries to 5.15.10+dfsg-5build1
  in noble-proposed

Status in qtbase-opensource-src package in Ubuntu:
  Fix Released

Bug description:
  After upgrading Qt5 libraries to 5.15.10+dfsg-5build1, several Qt5
  applications (including lxqt-panel and goldendict) crashed, leaving a
  "*** buffer overflow detected ***: terminated" message in console.

  It seems that the crashed applications all used the QSettings. The
  following sample code will crash with 5.15.10+dfsg-5build1, but not
  with 5.15.10+dfsg-5

  #include <QSettings>
  int main(int argc, char *argv[])
  {
      QSettings s("/tmp/a.ini", QSettings::IniFormat);
      s.setValue("a", 123);
      s.sync();
      return 0;
  }
