This one was fixed 3 months ago :

[BUG] stream_sock: BUF_INFINITE_FORWARD broke splice on 64-bit platforms
Yohan Tordjman at Dstorage found that upgrading haproxy to 1.4-dev4
caused truncated objects to be returned. An strace quickly exhibited
the issue which was 100% reproducible :
4297 epoll_wait(0, {}, 10, 0) = 0
4297 epoll_wait(0, {{EPOLLIN, {u32=7, u64=7}}}, 10, 1000) = 1
4297 splice(0x7, 0, 0x5, 0, 0xffffffffffffffff, 0x3) = -1 EINVAL
(Invalid argument)
4297 shutdown(7, 1 /* send */) = 0
4297 close(7) = 0
4297 shutdown(2, 1 /* send */) = 0
4297 close(2) = 0

Ah here's the reason. it was fixed between 1.4-dev5 and 1.4-dev6.
You should definitely upgrade to 1.4-rc1, it has many such issues
fixed, including this one of course !
