Description Jeff Johnson 2006-08-05 19:19:41 UTC
SSIA

Reproducer:
$ sudo strace -o /tmp/xxyz xrpm -qvv --requires --specfile time.spec
ptrace: umoven: Input/output error
ptrace: umoven: Input/output error
ptrace: umoven: Input/output error
/sbin/install-info  
/bin/sh  
/bin/sh  

(athough I've seen with every strace invocation in the last week or so)

SELinux is disabled if that matters.

$ rpm -qf /usr/bin/strace
strace-4.5.14-2.i386.rpm

Comment 2 Roland McGrath 2006-08-22 07:20:05 UTC
Please check the output.  Instead of -o, use > file 2>&1 and then look at the
part of the output near the "umoven" error message.  Does it refer to an
inappropriate syscall like sendto or another socket-related call that is not
what the program is really doing?

If so, this is the same as bug 202620, for which I already have a fix.

Here's the requested output:

read_exec_only:0, limit_in_pages:1, seg_not_present:0, useable:1}) = 0
set_tid_address(0x9c47898)              = 31449

{...}, 3220895864) = 0

This should be fixed in 4.5.14-3.
