MacOS crash by allow use Systemproxy



  • Hello again :)

    I use Qt5.8 with MacOS Sierra 10.12.1

    In our company we use Proxy to access Http / Https.
    By access to Http via QNetworkAccessManager MacOS popup the "Allow to use proxy Dialog". This is ok, we don't want to set proxy informations in Application code.
    But if i click allow, application crashes. Same by click allow any time.
    If i set the proxy in sourcecode, all works fine. But this is not the target :)

    Here is the Crashdump

  • It's clearly trying to access a null pointer. Could you share a minimum example to reproduce the error?



  • Old MacOS proxy issue https://bugreports.qt.io/browse/QTBUG-56747 ? Try Qt 5.9.0



  • @VRonin A simple Networkrequest produce this error. I download the Qt Installer, set Systemproxy, same crash :) Now i build Qt5.9 from source and test again



  • @tomma Thanks, yes, same error. I try 5.9 and post feedback.



  • Hello again :)

    the problem is still in the 5.9.0.
    Application crash by click "Allow" or "Always allow".
    If you click "Always allow", you can't start Application again without rebuild complete if he access to net.

    Qt Installer has same problem.


  • Lifetime Qt Champion

    Hi,

    Can you test that with the latest version of the 5.9 branch from https://code.qt.io ?



  • I downloaded again from official qt.io, Qt Installer crash by allow or set "Use system proxy".
