NetBSD-10.0/i386 spurious SIGSEGV

Hello

After upgrading i386 XEN3PAE_DOMU to NetBSD 10.0, various daemons
on multuple machines get SIGSEGV at places I could not figure any 
reason why it happens. Here is an exemple with nagios, but I see 
similar problems with apache httpd, sendmail, slapd, and even 
built-in syslogd and ping. This is a rare even that happens a 
few times a day.

Any hint how I could track this problem down?
