Mastering Regular Expressions (O'Reilly) has this to say:

"If you're working with embedded code or a dynamic regex, and your program
suddenly ends with an unceremonial

    panic: top_env

it is likely due to a syntax error in the code part of the regex. Perl
currently doesn't handle certain kinds of broken syntax well, and the panic
is the result. The solution, of course, is to correct the syntax."
