Installing the php7.0-bcmath package should be enough?

So far I was using PHP5, which was the version that had been installed
since Debian Jessie. So I just migrated to PHP7 to be able to install
the php7.0-bcmath package provided in Debian Stretch.

Unfortunately this did not make any difference.

A few seconds before the memory allocation error, syslog displays an
error on line 143 of /usr/share/php/Sabre/VObject/Reader.php. This is
the involved block:

----------
139         if (!$result) {
140             if ($options & self::OPTION_IGNORE_INVALID_LINES) {
141                 return null;
142             } else {
143                 throw new ParseException('Invalid VObject, line ' .
($lineNr+1) . ' did not follow the icalendar/vcard format');
144             }
145         }
----------

Does this suggest anything to you?

Thanks for your time.


Kind regards,
Daniel
