happens to (invalidly) have a regular expression
metacharacter as a subfield label, do not crash.

<datafield tag="650" ind1=" " ind2="0">
<subfield code="a">Dalziel, Andrew (Fictitious character</subfield>
<subfield code=")">xFiction.</subfield>
</datafield>
The error message associated with the crash is:
Unmatched ) in regex; marked by <-- HERE in m/) <-- HERE / at

Objects of type C4::Heading represent
headings and are (currently) initialized
from bib MARC::Field objects. A C4::Heading
has the ability via SimpleSearch to locate
the authority records that are either authorizing
the heading itself or contained more preferred
terms for the heading via See links.
