Thanks for trying it out, David. Unfortunately it isn't reproducible with a machine with 64 Gb of RAM or more. Yours, Cyrus On Mon, Jan 14, 2013 at 8:25 PM, David Winsemius dwinsem...@comcast.netwrote: On Jan 14, 2013, at 9:07 AM, Cyrus Shaoul wrote: No, Mehmet, I haven't tried that

Dear R-help list members, I am hoping to get you help in reproducing a problem I am having That is only reproducible on a large-memory machine. Whenever I run the following lines, get a segfault listed below: *** caught segfault *** address 0x7f092cc46e40, cause 'invalid permissions'

No, Mehmet, I haven't tried that yet. I was hoping to find out if there was some other option. I have no experience using LAPACK directly. I have looked into RcppEigen and RcppArmadillo, but have not tested them yet. If there are no other options, I guess I will go down that path. Thanks a lot,
