    Default QwtPolar Run examples crashed

    I'm using Qt 5.2 with Qwt 6.1 and QwtPolar. I have tried to compile example inside the QwtPolar package but failed.

    It keep showing this error:
    *** glibc detected *** /home/USER/qwtpolar/examples/bin/spectrogram: realloc(): invalid pointer: 0x00007fe0cc8df800 ***

    This stack is 100% Qt - unrelated to any Qwt functions. So this might be more an issue with your Qt environment.

    Hi Uwe,

    I have tried with previous Qt projects, there are no problem for running and debugging. I have tried with Qwt examples as well.
    I just installed QwtPolar and wanna try it out but failed. I keep getting this stack error.
    Do I need to reinstall Qt again to solve it?

    Thanks for your prompt reply.
