Ok, can you "git bisect" this, I'm not sure what else we could do to pinpoint the issue (as long as you don't have any obvious issues at build time, like a missing "make clean" before building) ... Change to the haproxy-1.5 (git) directory and start the bisect like this: git bisect start git bisect bad v1.5.1 git bisect good v1.5-dev21 Git will then select a commit approximately "in the middle" between dev21 and v1.5.1 and you can test it. If it works, enter: git bisect good otherwise git bisect bad and git will select another commit for you to test. In the end (after a few iterations of the above, git should come up with the bad commit). Regards, Lukas
