[Bug 985452] Re: apt-ftparchive fails on scanning large repositories

[Michael Vogt]

Strace shows that the pipe is not closed when the compressor child
exists:

$ strace -e trace=open,dup,close,pipe apt-ftparchive package. > /dev/null
open("./homer_clone_444.deb", O_RDONLY) = 5
pipe([261, 262])                        = 0
close(262)                              = 0
--- SIGCHLD (Child exited) @ 0 (0) ---

It seems like "AutoClose" in FileFd is set to false for compressed images which leads to "FileFd::Close()" not 
closing the internal iFD which then leads to this leak.
