Description Stephan Kulow 2011-09-28 10:45:45 UTC 
This is not a problem on x86_64, but on 32bit fuser is completely broken

Either fuser -v /dev/tty1 (just an example, it works for all devices) outputs
all processes or none. 

This very much looks like an uninitialized variable and valgrind blames timeout.c:182

Backing out the timeout patch fixes the problem for now.

Comment 2 Dr. Werner Fink 2011-10-04 11:24:03 UTC 
What exactly does valgrind blame ... as the vraible handle is
initialitzed and the pipes array should be also initialized
after start() has been executed (which in fact is done as
constructor or due restart of the forked subprocess)
Comment 3 Stephan Kulow 2011-10-04 11:45:10 UTC 
I have no time to debug this for you, sorry.
Comment 4 Dr. Werner Fink 2011-10-04 13:17:02 UTC 
On which system and with which gcc do you see this?
As I do *not* see this behaviour ...
Comment 5 Stephan Kulow 2011-10-04 15:59:27 UTC 
I've seen it on _all_ i586 systems running factory. fuser /dev/snd/* returned all processes.
Comment 6 Dr. Werner Fink 2011-10-05 09:25:34 UTC 
The message of valgrind is nonsense ... the real reason is the internal type
of structure stat used by glibc on i386 which in fact is struct stat64 !
Comment 7 Dr. Werner Fink 2011-10-05 09:38:03 UTC 
psmisc/psmisc-22.14> sudo src/fuser -v /dev/tty1
                     USER        PID ACCESS COMMAND
/dev/tty1:           root      17685 F.... mingetty
psmisc/psmisc-22.14> uname -i
i386

that's it
