[Bioc-devel] edgeR crashes when xlsxjars is loaded

I have found an issue where having the xlsxjars package loaded kills the 
entire R session with a segfault when "edgeR::estimateDisp" is called on 
my dataset. The issue seems to be specific to my data, since a random 
integer matrix of identical dimension does not trigger the bug. Other 
than being derived from ChIP-Seq input samples, there is nothing special 
about my data that I know of.

I have prepared a test case with a subset of my data that reproducibly 
triggers the crash. You can find the data and script to reproduce here:
