Greetings; I've posted the following to R's bug tracking system (at https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17210 ) and Martin Maechler requested that I post to this list as well. If I start R from the command line with --vanilla, then repeatedly execute the following line:
det(matrix(nrow=10,ncol=10)) ... I eventually get a crash, with error: *** Error in `/usr/lib/R/bin/exec/R': malloc(): memory corruption: 0x0000000002399400 *** The specific address in memory that is referenced varies. The number of times I need to execute the above line before getting a crash also varies. This occurs with a wide range of matrix dimensions; 10x10 is not the only size that causes this issue. output of R.version: platform x86_64-pc-linux-gnu arch x86_64 os linux-gnu system x86_64, linux-gnu status major 3 minor 3.2 year 2016 month 10 day 31 svn rev 71607 language R version.string R version 3.3.2 (2016-10-31) nickname Sincere Pumpkin Patch I am running Linux Mint 17.3; my CPU is an Intel Core i7-2620m (Sandy Bridge). My RAM is non-ECC. My R binary is from the CRAN Ubuntu repository at cran.cnr.berkeley.edu . (r-base and r-base-core versions 3.3.2-1trusty0 ) I also see this issue running R within Emacs, as well as Rstudio. This issue may be related to https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16862 but I'm not certain. The output of La_version() for me is: [1] "3.5.0" The output of: system(paste("lsof -p", Sys.getpid(), "| grep -iE '(blas|lapack)'")) is: R 3636 <myusername> mem REG 252,0 39272 11930369 /usr/lib/R/modules/lapack.so R 3636 <myusername> mem REG 252,0 5882272 11933488 /usr/lib/lapack/liblapack.so.3.0 R 3636 <myusername> mem REG 252,0 23108112 11929607 /usr/lib/openblas-base/libopenblas.so.0 Is anyone able to reproduce?
