fusecompress crash

[leolivier]

Hi,
Built fusecompress on Linux Mint 19.
I do:
$ cd /backup;
$ mkdir fc fcu
$ fusecompress -o fc_d fc fcu

In another terminal, I do:
$ cp x.txt /backup/fcu
==> crash of fusecompress with the following stacktrace:

FuseCompress::mknod name: x.txt
FuseCompress::mknod inode: 41293005
new CFile(..., x.txt)
C (x.txt), raw/user 0x19/0x0 bytes
getattr name: x.txt, m_IsCompressed: 1, m_fh.size: 0x0
Memory::getattr(0x7fc0fc001350) m_FileSize: 0x0, m_FileSizeSet: 0
virtual Compress::~Compress(), x.txt
new CFile(..., x.txt)

FuseCompress::open 0x7fc104001230 name: x.txt
File::open file 'x.txt', inode 41293005, m_refs: 1
Compress::open m_refs: 1
getattr name: x.txt, m_IsCompressed: 1, m_fh.size: 0x0
*** stack smashing detected ***: terminated
Abandon (core dumped)

So I unmounted fcu:
$ fusermount -u /backup/fcu
then restart fusecompress (as above)
then:
$ ls /backup/fcu

x.txt
$ ls /backup/fc
x.txt
$ more /backup/fcu/x.txt

Again, crash with the stack:

I'm getting the same issue, resulting in Software caused connection abort and Transport endpoint is not connected errors.

This repo is abandoned so not sure we'll get a fix unless some enterprising soul picks it up. Really keen on using this to try to ddrescue a sparsely-used 5TB drive onto a smaller drive.
