[BioC] memory invalid permission with qc()

[Simon Noël]

Hello.  I have some problem using qc().  I have an old data set that work
perfectly with qc() but a nuw one just arrive from affymetrix and I am not able
to run qc() on it.  I use the code :

library(affy)



library(affyio)


library(simpleaffy)

Data <-ReadAffy()

qc <- qc(Data)

and I recive this error message :

*** caught segfault ***
address 0xb6cf9000, cause 'invalid permissions'

Traceback:
 1: .C("GetExpressionLevels", as.double(pms[, x]), as.double(mms[,     x]),
as.character(pns), as.integer(length(mms[, x])), as.double(ct),    
as.double(st), exprs = double(length(unique.pns)), length(unique.pns),    
PACKAGE = "simpleaffy")
 2: FUN(1:2[[1L]], ...)
 3: lapply(X, FUN, ...)
 4: sapply(1:length(pms[1, ]), function(x) {    .C("GetExpressionLevels",
as.double(pms[, x]), as.double(mms[,         x]), as.character(pns),
as.integer(length(mms[, x])),         as.double(ct), as.double(st), exprs =
double(length(unique.pns)),         length(unique.pns), PACKAGE =
"simpleaffy")$exprs})
 5: justMAS(x, tgt = sc)
 6: call.exprs(unnormalised, "mas5")
 7: qc.affy(unnormalised, ...)
 8: qc(Data)
 9: qc(Data)
10: eval.with.vis(expr, envir, enclos)
11: eval.with.vis(ei, envir)
12: source("tmp.R")

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

What should I do to correct the problem?
