in thread Segfault with MooseX::Declare and Regexp::Grammars

You're not the only one to load Data::Dumper :)
print "AH Data::Dumper::VERSION $Data::Dumper::VERSION @_\n" +;
AH Data::Dumper::VERSION 2.128 Foo=HASH(0x1bc0a2c) HASH(0x1bc0afc)
Data::Dumper may or may not be responsible, directly or otherwise ... someone needs to bust out a debugger and track down where the segfault occurs
