Public bug reported:
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;
}
