Bisect points to commit 3d033384b2016a58c3eed89524dc658660c759ce Author: Zefram <> Date: Thu Dec 14 04:23:58 2017 +0000 warn on $a.$b.$c in void context $a.$b.$c gets transformed early on to execute as ($a.$b).=$c, which didn't warn about void context becuase .= looks like a useful side effect. Happily, the recently-added OPpCONCAT_NESTED flag identifies that this has happened. Make scalarvoid() pay attention to this flag when a concat op is put into void context. Fixes [perl #6997]

It's an amusing combination of oversensitive tests (barfing on the warnings) combined with some code that's unintentionally putting a concat operator in void context. The problem is concerned with this code in Fsdb::Filter::dbcolstats: croak $self->{_prog} . ": target column " . $self->{_target_column} . " is not in input stream.\n" if (!defined($self->{_target_coli})); This code would be correct, except for the fact that croak() hasn't been imported into the package. This being Perl, the lack of importation doesn't make this a compile-time error, but does change how the code parses: "croak $self" parses as an indirect method call, and the concatenation becomes the top-level operation. This used to not even warn, but since 5.27.7 there is a correct warning about concatenation in void context. The fix is for that module to import croak(). -zefram
