I don't have a direct answer on your observed problem, but I would
point out that judging by my archives, the use of the http_proxy
option is /extremely/ underrepresented on this list. I have no
information if this might be the case, but I suggest that it would be
possible for a bug to creep in and remain hidden for longer in this
code path because of its relative rareness.

This mean-time-to-bug-discovery might be compounded by the very
(very!) broad demographic generalisation that people using this
simplistic feature of haproxy /might/ be less inclined to upgrade for
feature-based reasons, due to their architectures perhaps relying less
on a fully-featured proxy being inline.

In the absence of any other information, my next steps in your
situation would be to see if I could replicate this problem in a
different haproxy mode, not using option http_proxy.

I absolutely recognise that that might not be possible, and I'm sure
others on the list will help you discover the true root cause of the
problem. I only mention it as it might not be obvious that this isn't
a commonly discussed, hence maybe used, feature of haproxy.
