Reference Number: DPD200240885
Version: Intel® C++ Composer XE 2013 Update 2 (Intel® C++ Compiler XE 13.1.0)
Operating System: Windows* and Linux*
Problem Description:
If the word "simd" is used as an identifier in C/C++ code (for example, as a typename, or as a function parameter name), there is the chance that the compiler may treat this identifier as a reserved attribute keyword and you will then run into compilation errors. This issue should only result in compilation errors. Link-time or runtime problems are not expected. An example follows:
$ cat test-simd.cpp
void foo(float * simd);
$ icc -V -c test-simd.cpp

Problem Resolution:
This is a known issue that may be resolved in a future product release. As a workaround, change the identifier to a non-reserved keyword that is not "simd". If this workaround is not feasible, please contact Intel® Premier Support at https://premier.intel.com.
