update.php crashes while collecting CPU stats

[Ralf Hildebrandt]

Package: serverstats
Version: 0.8.2-2
Severity: important

% /usr/share/serverstats/update.php
Working on cpu
Segmentation fault

in dmesg I see:
[9843815.435851] update.php[32627]: segfault at bf3f1fc4 ip b7d5e8fc sp bf3f1ea0 error 6 in libpcre.so.3.12.1[b7d4d000+30000]

Poking around in cpu.php I found that:
preg_match('/^([a-zA-Z0-9]*)((\s+([0-9]+))+)\s*$/i', $line, $parts)
would crash when it encounters the $line:

I confirm that serverstats is also unusable here.
