QwtPolar Run examples crashed

[cr7tiano]

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 ***

I cant find similar error in this forum. Hope some one can help =)

Thanks.

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.
