[BioC] justRMA segmentation fault when calculating expr.

Hi everybody,
I know that this has been reported before but I haven't seen any solution.
I have been consistently getting segmentation faults whenever I use 
justRMA with a cdf environment other than the standard affy cdf 
environments (for instance hgu133).
I have tried using my own alt cdf environments and Laurent Gautiers' 
altcdfenvs at "http://www.cbs.dtu.dk/staff/laurent/download/maprefseq/"
Everything goes fine until the calculation of expression. I have tried 
with both destructive = TRUE and destructive = FALSE (rma_c_complete
vs. rma_c_complete_copy), the fault persists.
When I use the default affy environment it works fine.

 > exprs 
<-.Call("rma_c_complete",probeintensities$pm,probeintensities$pm,probenames,ngenes,body(bg.dens),new.env(),normalize,background,bgversion,
+     PACKAGE="affy")
Background correcting
Normalizing
Calculating Expression
Segmentation fault


Did anyone experience such a thing?

I am using R 2.0, and the latest version of affy.

thanks.
