Hi,I was not able to reproduce this neither in sbuild nor on my local system and reproducible builds doesn't show failures either. Interestingly debuild asked for bison, whereas sbuild installs neither flex nor bison. Maybe we should add both as build dependencies..
Can you send a full build log and the versions of the installed build dependencies?
