It is also in 12.0(26)S1 and 12.0(24)S4, if that helps.  And in 12.2(20)S,  
I believe.

I used the Bug Toolkit on CCO, and it told me

Symptoms: A Cisco router may reload when you add Border Gateway Protocol  
(BGP)
neighbor statements to the configuration.

Conditions: This symptom is observed on a Cisco router that runs Cisco IOS
Release 12.0 S or Release 12.2 S when BGP neighbors are added by using a  
script
that adds the BGP neighbors at a much faster rate than manual addition, and
when a large BGP table is already present on the router before the script  
adds
the BGP neighbors.

Workaround: There is no workaround.

I have no first-hand experience with this bug, but from what I see in the  
internal bug notes, that looks about right.  So at a guess, if you were  
cutting and pasting a config with a large number of neighbors (FSVO  
'large', I suppose), just do them one at a time.  But that's just a  
guess.  blah blah disclaimer blah blah contact your support representative  
blah blah blah etc...:)
