      "summary": "DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName.\n\nfetchrow_hashref uses the string pointer of the FetchHashKeyName attribute as the key name without stringifying it first. When FetchHashKeyName has been set to an integer (IV) or floating-point (NV) value, that pointer is invalid, so reading the key name triggers a segmentation fault.\n\nThis can be triggered with the following code:\n\n   my $dbh = DBI->connect( \"dbi:ExampleP:\", \"\", \"\",\n       { RaiseError => 0, PrintError => 0 } );\n   $dbh->{FetchHashKeyName} = 42;\n\n   my $sth = $dbh->prepare(\"select mode, size, name from .\");\n   $sth->execute;\n   $sth->fetchrow_hashref;",
