Problems using std::bind with icc/icpc 14.0.2 and gcc 4.8

I have had a some problems in the past using icc/icpc with gcc 4.8 as described here. It appears that the problem has been partially fixed with the release of 14.0.2 however I am still having problems with std::bind and as a result am unable to compile code that is using a Boost library. This problem has also been reported here. I am running 64-bit Xubuntu 13.10 but that user is running openSUSE 12.3. As a test case consider the code below:


For my Linux applications, I like to embed compiler information into the executables.  For the Intel compiler, the __INTEL_COMPILER and __INTEL_COMPILER_UPDATE pre-processor macros give me what I want.  However, I also like to embed the GNU compatibility information, too.  __GNUC__ and __GNU_MINOR__ give me accurate information, but __GNUC_PATCHLEVEL__, while defined, does not contain the correct value.

simple cilk_spawn Segmentation Fault

I'm having difficulty running a simple test case using cilk_spawn.  I'm compiling under gcc 4.9.0 20130520.

The following fib2010.cpp example, executes in 0.028s without cilk and takes 0.376s with cilk as long as I set the number of workers to 1.  If I change the number of workers to any number greater than one, I get a segmentation fault.
