What version of Acme::EyeDrops are you using? This sounds like perl RT bug #23143, namely:

The following program works under Perl 5.8.0 but fails under 5.8.1-RC2 with the error: "panic: pad_free curpad". 
''=~m<(?{eval'print 4;$_=9'})>;($_)=9;

[download]
If you change it to: 
''=~m<(?{eval'print 4;$_=9'})>;$_=9;

[download]
it works fine.
This perl bug was worked around in Acme::EyeDrops 1.42 and later, by never using $_ in filler code.
