sysinfo locks on startup

Bug Description

I've installed the 'sysinfo' program. But it locks up on early startup. Even running with "-h" or "--help" flags it locks up with the same behavior. When locked the process uses 100% cpu.

Watching it with strace, it does a lot of work, but comes to a dead stop after reading /proc/cpiinfo. I let it run for 10 minutes with no results.

Package: sysinfo
Priority: optional
Section: universe/utils
Architecture: i386
Version: 0.6.1-0ubuntu1

I'm still experiencing this problem with the latest dapper version. I'll attach a strace log, but I'm not sure what else I can report?

This is the log of tracing sysinfo. It completely hangs at this point with no further results. It uses 100% cpu while hung.

yes, it fixed another bug. could you attach your /proc/cpuinfo maybe? (i'll contact upstream to have a look at this issue, but the development of this c++ application was terminated, and a new mono-based version was launched)

/proc/cpuinfo file. This is from a Pentium4 with hyperthreading.

I see the a similar problem on ppc. In my case it has problems reading /proc/bus/input/devices. ltrace shows repeated calls to getline and strstr:

...
_ZNSi7getlineEPcic(-156456, -156536, 80, 10, 68) = -156456
strstr("", "Name") = NULL
_ZNSi7getlineEPcic(-156456, -156536, 80, 10, 68) = -156456
strstr("", "Name") = NULL
_ZNSi7getlineEPcic(-156456, -156536, 80, 10, 68) = -156456
strstr("", "Name") = NULL
_ZNSi7getlineEPcic(-156456, -156536, 80, 10, 68) = -156456
strstr("", "Name") = NULL
_ZNSi7getlineEPcic(-156456, -156536, 80, 10, 68) = -156456
strstr("", "Name") = NULL

I found a workaround for both problems. This package should provide a fix for them.

I can confirm the new release is working. 0.6.1-0ubuntu4 is running great. This is the first version I have been able to start in a long time.
