Package: sane-utils Version: 1.0.22-7.4 Severity: normal Dear Maintainer,
I tried to use my scanner (CanoScan LIDE 25) connected to pc A using the net backend on pc B. When I try to detect the scanner on B I ran into segfaults, memory corruptions and other strange messages. On my research I found the bugs #586665 and #734103 which describe some similar behavior. In fact as soon as I try using `scanimage -L` to detect the scanner I get a segfault as root. As a normal user it seems to work as expected: The scanner gets found without problems. It seems that the probelm arises before the pc A gets contacted, in the log of A there is no trace of B if root calls scanimage. To allow root to scan (or possibly other users) one has to preload the libpthreads library. For example if I call > LDPRELOAD=/lib/x86_64-linux-gnu/libpthread.so.0 scanimage -L then root can also find (and use) the scanner. A quick ldd output shows that scanimage does not load libpthread in any form. Thus it might be sufficient to add a compiler flag.
