Bus errors (access violations in text, e.g. JMP) and segmentation 
violations (access violations in the data or stack) may be due to bad 
memory. You can test this out by copying ntpd from a working system to the 
other. Use pkg_create to create a binary package on the working system and 
pkg_add on the other.

You may want to check out configuration on the non-working system.

In regard to debugging mode, the code will use a different execution path 
and your memory map will be slightly different, bypassing tickling whatever 
causes ntpd to crash.

Personally, I haven't had problems with Perl 5.12 either. My infrastructure 
is at 5.14 currently but when it was at 5.12 I had no issues either.
