The above program hangs in most bleadperls I have. The C:R:PrereqCheck
module loads the moduls it gets on stdin. When Params::Classify and
Module::Runtime come in this order, exporter gets involved, plenty of
redefined warnings are spit out, finally the line is reached that has
already been discussed in the 72743 ticket. But I never see a coredump
there, I always see a process that consumes 100% CPU forever.

(eval 7):1
I have no overview under which perls it happens and which not. There is
no pattern yet visible for me. It is very frequent among perls but not
very frequent per smoker because the situation is only triggered when my
smoker tries to install Lexical::Import.
HTH,
