[Avodah] Pesach Sheini

[David E Cohen]

If Mashiach were to come between 14 Nisan and 14 Iyar, would everybody bring
the pesach sheini that year?

My understanding is that we would not.  From the case that's dealt with on
the bottom of Pesachim 90a (brought in Hilkhos Korban Pesach 7:4), we seem
to have an ironclad rule that nobody brings pesach sheini unless a majority
of the tzibbur brought pesach rishon that year.

This morning, however, I happened to be glancing through the Chabad "Devar
Malkhus" pamphlet, which had a transcript of a conversation that the
Lubavitcher Rebbe zt"l had with R' Avraham Shapira zt"l and R' Mordekhai
Eliyahu yblct"a when they visited him.  One of them said something along the
lines of "if Mashiach comes before Pesach Sheini, and the Rebbe comes to
Eretz Yisra'el to bring the korban pesach..."

I haven't been able to find anywhere where this question is discussed
explicitly.  Can anybody point me in the direction of somewhere where it is
discussed?
