We're currently at libical-3.0.8 and I haven't been able to reproduce
this issue. If it comes up again we'll see what we have to do to fix it
or work around it.

In the last month, libical has non-deterministically failed twice, once
on i686 and once on mips64el, with the same error in the same place:

Only the first few lines of the error output is shown above.  It is
followed by many lines of similar errors in 'ical.h'.

Restarting the builds later resulted in success.

Perhaps a parallel build issue?
