Looks like bug in ical.
Thanks for a bug report. It is quite unlikely this being a bug in the libical itself, I guess the problem is that the passed in time structure contains invalid date, which causes read out of the array boundary. Do you have any reproducer for this, please? The backtrace data suggests that this is related to the Birthdays & Anniversaries calendar, one of your contacts having Birthday.
