FWIW, "was going to compile" part does not make it clear (to me) whether 
you did actually compile/test v6.3.

If the above output is from Squid v6.3, then you may have found a v6.3 
problem that we do not know about. Please share the HTTP request that 
triggers the above output.

Otherwise, please try to upgrade to Squid v6.3 because its commit 
6695897 is meant to fix a v6.1 bug with the above symptoms.


Thank you,

Alex.
