It seems that this is a locale problem. I've got this messages: bad data in /proc/uptime bad data in /proc/loadavg Recompiling didn't help, 'LC_ALL=C top' works OK.
Damn! The subject should be (crash example): LC_ALL=cs_CZ top
Created attachment 1592 [details] strace of running top with LANG=sv_SE
I could reproduce this bug with LANG=sv_SE too. Attached a strace.
Fixed for beta5 (procps-2.0.7-2)
