[v4.7.2] Leak with static QMessageBox?



  • Hi!

    Simple code in a minimal example already: QMessageBox::warning(this, "TEST TITLE", "TEST TEXT");
    Running it over and over again, watching "Private Bytes" in Process Explorer @WinXP.

    Result (KB):

    Box closed | Box opened
    Box closed again | Box opened again
    ...

    2236 2328 (+92K when opening box, -36K when closing box) (program start)
    2292 2340 (+48, -40)
    2300 2348 (+48, -40)
    2308 2348 (+40, -40)
    2308 2348 (+40, -40)
    2308 2356 (+48, -40)
    2316 2356 (+40, -40)
    2316 2364 (+48, -40)
    2324 2364 (+40, -40)
    2324 2364 (+40, -40)
    2324 2372 (+48, -40)
    2332 2372 (+40, ...

    U see, sometimes there's more being allocated than deleted.
    Can't be normal, is it?



  • Hm... this is strange. Have you run the test on other computers and/or OS? May be you should reported it as a bug?

    Best regards,
    Leon
