The error only happens when debugging with the "Run in Terminal" option selected in the Project settings. The program runs normally if executed standalone in the gnome-terminal. Any idea for what might be causing this?

Hello Ashish,

thank you for your report.

This seems to be related to these two issues:
https://bugreports.qt.io/browse/QTCREATORBUG-25082
https://bugreports.qt.io/browse/QTCREATORBUG-25227

In the latter, Christian asked for a small example project. In case you 
can provide one, it would be nice if you could upload it to the report.

Cheers,
Robert
