Comment:

 for reference, the link that i originally discovered this with:
 http://www.softpanorama.org/People/Torvalds/Finland_period/xenix_microsoft_shortlived_love_affair_with_unix.shtml


 problem was slightly different when running inside gdb, but seems like
 it's probably still the same basic issue:

 from within gdb, the crash did not occur on paste, but rather when editing
 the pasted text: adding more underscores to make the string even longer
 (but still "unwrappable") crashed it.  i reproduced this multiple times
 before gathering the following backtrace.
