"cookie" =~ m/$a/;
panic: restartop

This is perl, v5.8.7 built for x86_64-linux
This is perl, v5.8.7 built for MSWin32-x86-multi-thread (^Z in this case)
This is perl, v5.8.7 built for cygwin-thread-multi-64int

I think I can safely say the cause of the problem is the unterminated string
in the code expression.
Bandaid? Check for unterminated strings in code expressions.
Beyond that, I have no idea.

This was found thanks to a piece of code that loads pairs of regexps and
eval strings from a file - one of the regexps used (.+)\b(?(?{!defined
$refs{'ntla}->{$1}})^) to find things that are defined in the ntla entry -
fun times.
