Description (last modified by dmik)

Finally I found the bug, which cause QT application trap on my notebook, when using file dialog. It is strange that this mistake doesn't cause trap on desktop PC ;)

Here is the fixed version of QDir::rootDirPath() function: 

QString QDir::rootDirPath()

{
    ULONG bootDrive[1] = {0};

    DosQuerySysInfo( QSV_BOOT_DRIVE, QSV_BOOT_DRIVE, (PVOID)bootDrive, sizeof(bootDrive) );

    QString d = QChar( (char)(bootDrive[0] + 'A' - 1) );

    d += ":/";

    return d;

}

This bug has already been fixed in r123. You should update from SVN more often :) But thank you anyway, it was a nasty typo. It may not cause traps on your desktop PC because you have the HOME environment variable set there, as opposed to your notebook.
