This seems to be a new issue. Can you attached your design.qar file for investigation?

If you want to attached privately, let's us know.

Thank you,

our customer doesn't allow us to send you the code.

We changed some settings in the compiler flags and now it works again. But we don't know why.

kind regards

Mike
