XML::Bare versions through 0.53 for Perl will hang in an infinite loop when parsing malformed attributes.
The parserc_parse function never advances the attribute-parse state cursor on certain malformed attribute forms, looping forever.
Nameless attributes such as "<a ='c'>" or unbalanced quotes "<a b='''''''c'>" can trigger this condition.
