Dear R developers, (Apologies about previous incomplete e-mail, I fat-fingered a keyboard shortcut)
I recently upgraded to 3.2.3 and am getting mystifying errors with my in-development code (available at https://github.com/gertvv/gemtc/tree/feature/regression). Every few hundred LPs that I solve using the rcdd package will result in a SEGFAULT in the garbage collector (address 0x10, cause 'memory not mapped') or an error about a list not existing. Downgrading to 3.2.2 works, but *only* after completely removing my local R packages and re-installing them. A subsequent upgrade to 3.2.3 will again be broken, and even more mysteriously it will also break a re-downgrade to 3.2.2 until I again purge my local packages and re-install them. To downgrade I am using (with the CRAN ubuntu mirror enabled): sudo apt-get purge r-base-core sudo rm -rf ~/R sudo apt-get install r-base-core=3.2.2-1trusty0 r-base-dev=3.2.2-1trusty0 r-recommended=3.2.2-1trusty0 sudo apt-get install r-cran-rjags R -e "install.packages(c('devtools','igraph','meta','truncnorm','rcdd'))" The code that produces a SEGFAULT (usually after 5-15 iterations) under 3.2.3, but not 3.2.2: library(devtools) load_all('gemtc') for (i in 1:100) { print(i); mtc.model(thrombolytic) } (note that the SEGFAULT also happens without devtools) The sessionInfo() in 3.2.2: R version 3.2.2 (2015-08-14) Platform: x86_64-pc-linux-gnu (64-bit) Running under: Ubuntu 14.04.3 LTS locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=nl_NL.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=nl_NL.UTF-8 LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=nl_NL.UTF-8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=nl_NL.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] gemtc_0.8 coda_0.16-1 lattice_0.20-33 devtools_1.9.1 loaded via a namespace (and not attached): [1] Rcpp_0.12.2 roxygen2_5.0.1 rcdd_1.1-9 digest_0.6.8 [5] truncnorm_1.0-7 grid_3.2.2 plyr_1.8.3 meta_4.3-2 [9] magrittr_1.5 stringi_1.0-1 rjags_4-4 tools_3.2.2 [13] stringr_1.0.0 igraph_1.0.1 memoise_0.2.1 A core dump is here: https://drive.google.com/a/rug.nl/file/d/0BxhVLNPmwLrycTYtOHNxNXZTMEk/view?usp=drive_web I have tried debugging this but am stumped. Any help would be greatly appreciated!
