@maribu , the b87f8a8 will pass in this PR and it will fail at master with an stack overflow.
BOARD=atxmega-a1u-xpro make all flash term
I couldn't think a simpler use case to force the condition that generate the stack overflow. It was really hard to setup the right condition. Right now, this can be tested with ATxmega. I not expect that this snip passes on CI and my intention is only present a possible use case that exploit the issue.
