[BioC] Segfault in affy:rma() with custom chip

Hi All,

We have a custom Affy chip that has some very long probesets (~300 probes).
When I try to use rma on this data, a segfault is thrown, expresso() does
not exhibit this problem, but is of course, much slower.

Is there a built-in size restriction on the number of probes in a probeset
somewhere within RMA?
