Hello, Does the -fstack-protector option work on CLANG 3.1 and 3.2? There is thread on FreeBSD forums about the stack protector and ports and I'm wondering if it's possible to use the -fstack-protector option with CLANG. http://forums.freebsd.org/showthread.php?t=36927 -Kimmo

Hi All, Users have contacted me because they can not build MCMCglmm from source. All are using R 3.3.0 on various machines with different compilers gcc (Ubuntu 5.4.0-6ubuntu1~16.04.2) 5.4.0 g++ (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4 Mac OS X El Capitan (version/compiler unspecified) The issue seems to be with mixing C/C++ with the repeated error: /usr/include/c++/5/bits/cpp_type_traits.h:118:3:

This looks like the result of including a C++ system header inside an extern "C" block. There is no evidence of this happening in the current version 2.22.1. However, it did happen in the previous version 2.22 via the chain of inclusions: MCMCglmmcc.h -> cs.h -> R.h -> various C++ system headers See Writing R Extensions P 108. I would check that the people reporting this bug

Dear LLVMers, I am trying to measure the performance overhead (if any) of the canaries that clang inserts in the code. I would like to do this automatically, using the LLVM test infra-structure. However, I am not sure if that is possible. Could someone tell me which flags in the TEST.nightly.Makefile script, (or any other script) I must change to have this done? Usually I insert canaries with

Hi, I ran R (version 2.9.0) CMD build under root in Fedora (9). When it tried to remove "junk files" it removed EVERYTHING in my local account! (See below). Can anyone tell me what happened, and even more importantly if I can I restore what was lost. Panickingly, Jarrod [jarrod at localhost AManal]$ R CMD build MCMCglmm_2.05 * checking for file

...ion ------------ Stack Smashing Protection (SSP) aims to protect against buffer overflow attacks by placing a 'canary' value on the stack that is validated upon exiting a function. LLVM currently supports SSP. Specifically it supports two modes: -fstack-protector-all - enables stack protectors for all functions -fstack-protector - Uses a heuristic to apply stack protectors only to functions that need it - The heuristic checks for: character arrays >= SSP_BUFFER_SIZE (default:8-bytes) aggregates containing arrays >= SSP_BUFFER_SIZE * alloca >= SSP_BUFF...

...If the LLVM /Clang community wants this feature so that it is feature-compatible with GCC, then I think including this feature into LLVM/Clang makes sense. If you want to protect applications from attack, then I think there are far more productive and interesting things to work on than stack protectors. Stack protectors are really a hack and, at best, only protect against a single kind of attack (and with buffer overread attacks, I'm not even sure if they do that very well). Even if they work against stack buffer overflows, stack protectors don't protect the application from heap ov...

Hi, List, In checking the page fault problem when using pv-grub to start domU in opensuse12.3[1], found that the problem is caused by ''-fstack-protector'' flag which is introduced in rpm build: export EXTRA_CFLAGS_XEN_TOOLS="$RPM_OPT_FLAGS" export EXTRA_CFLAGS_QEMU_TRADITIONAL="$RPM_OPT_FLAGS" export EXTRA_CFLAGS_QEMU_XEN="$RPM_OPT_FLAGS" with

Hello, I am getting a fresh CentOS 6.7 machine set up with all of the goodies for R 3.2.3, including dplyr package. I am unable to successfully install it. Below I show the failed installation using utils::install.packages() and then again using devtools::install_github(). Each yields an error similar to the other but not quite exactly the same - the error messages sail right over my head. I

Hi all. For a while, gcc has supported a stack protection mechanism (-fstack-protector and friends, available in gcc 4.1.2 and up). Can anyone think of a good reason not to enable it if the compiler supports it? A quick test here shows minimal difference in runtime over a full regress pass (~10sec over 8.5 minutes, and since the machine is not entirely idle that could be experimental error).

Hello, I am having errors when I try to install RSPerl-0.92 under fedora 14.

You normally see these errors when compiling on a vm that has very little memory.
