...plication of sweep or the product ("*") function on an LIMMA MAList object. To my knowledge, limma does not define a "*" method for MAList objects. If only LIMMA is loaded but not package xlsx, the code does not crash but rather produces an error ("Error: C stack usage 7970512 is too close to the limit"). Loading only package rJava instead of xlsx does also not produce the crash but the error message instead. Note that xlsx functions are not explicitly used. It could be reproduced on two different Linux machines running R-3.2.5, R-3.3.0 and R-3.3.2. Code to re...

Hi, following up on my own question, I found smaller example that does not require LIMMA: setClass("FOOCLASS", representation("list") ) ma = new("FOOCLASS", list(M=matrix(rnorm(300), 30,10))) > ma * ma$M Error: C stack usage 7970512 is too close to the limit > library(xlsx) Loading required package: rJava Loading required package: xlsxjars > ma * ma$M ---> Crash xlsx seems to act like a catalyst here, with the product operator running in a deep nested iteration, exhausting the stack. Valgrind shows thousands of...
