It would help if you submit the bug through perlbug. (with a more descriptive title than this post :-) )

That's pretty nasty code by the way: you should be using something like

perl -e'print map { scalar reverse } reverse <>'
#or
perl -e'print scalar reverse for reverse <>' perlbug.txt

Ofcourse, those don't segfault.. :-)
