This fails because RRULE2toInternal() in rrule.cpp fails to convert the
RRULE properties into the internal format. It bombs out here:
switch (freq)
{
...
case 'Y' :
if (byday == "" ||
(byday.length() == 2 && byday[0] ==
RRULE_weekdays[startwday][0] &&
byday[1] ==
RRULE_weekdays[startwday][1]))
{
...
}
else
{
goto incompat;
}
It reaches the "goto incompat" because byday == "-1SU".
Recurrence rules with "last day in month ..." are common for VTIMEZONEs.
Beat, is that really something that is not handled by the Synthesis code
at the moment? What would be necessary to add support for it?
