Here's the log:

Here I'm pasting the diff to add patches to RSB:

You can apply the above diff into your rtems-source-builder and try to
build couverture qemu.
Most likely it will fail it seems.

For now, I suggest you to use --rtems-bsp=leon3-sis-cov instead of qemu,
this is give you the reports and you can start focusing on your main ticket.
