Hello everyone.
I've just found a bug in inets http-client (or somewhere in chunk decode
routines). It is reproduced when a remote http-server sends zero-length
response:
goryachev@goryachev:~% erl
Erlang (BEAM) emulator version 5.5.3 [source] [async-threads:0] [hipe] [kernel-poll:false]
Eshell V5.5.3 (abort with ^G)
