Comment (by geoff):

 OK, I've tested this patch with 4.0.3 now (git checkout varnish-4.0.3 and
 then build), and I'm still getting the error. varnishtest fails with a
 gunzip error -- I'll attach another log of the test run.

 The synthetic part does not appear within a chunk in the midst of gzipped
 data, but rather in a separate chunk, without any other binary data in
 that chunk:

 {{{
 **** c1    0.5 len| 0015\r\n
 **** c1    0.5 chunk|
 \x1f\x8b\x08\x00\x00\x00\x00\x00\x02\x03\xb2\x89\x88\x8c\xb2\x03\x00\x00\x00\xff\xff
 **** c1    0.5 len| 0032\r\n
 **** c1    0.5 chunk| this is the body of an included synthetic response
 **** c1    0.5 len| 0019\r\n
 **** c1    0.5 chunk|
 \xb2\xd1\x8f\x88\x8c\xb2\x03\x00\x00\x00\xff\xff\x01\x00\x00\xff\xff\xa3\x8d\xb7\xdd\x0b\x00\x00\x00

 **** c1    0.5 bodylen = 96
 }}}
