"does not work" is surely defined by the comment above the failed regex:

  # in case the last line was huge, trim it back to around 200 chars

and "{,2}" does not work to trim the line in earlier version of perl either.

To trim the line to 200 chars "s/^(.{0,200}).*$/$1/gs" should be correct.



Any reason why something so basic has been left for 8 month?  Is spamassassin
unmaintained?

Unescaped left brace in regex is deprecated here (and will be fatal in Perl
5.30), passed through in regex; marked by <-- HERE in m/^(.{ <-- HERE
,200}).*$/ at /opt/xxxx/lib/perl5/xxxx/Mail/SpamAssassin/PerMsgStatus.pm line
921.

Note: and will be **fatal** in Perl 5.30
