Internal Error: Bad Pointer

[dnesteruk]

I'm attempting to compile the attached file with icpc -mmic -openmp offload.cpp. Unfortunately, I get the following error:

offload.cpp(9): internal error: bad pointer
    #pragma omp target map(inarray[0:SIZE]) map(sum)
    ^

Help much appreciated! FYI, I'm using 2013.4 toolset on Linux.

I reproduced the error with the earlier 2013.4 release you used and confirmed it is fixed in the latest Composer XE 2013 SP1 Update 2 release (See below).

The OpenMP 4.0 target directives are not intended for use with the -mmic option. You compile this program without that option.

Thanks, simply removing the -mmic flag helped me compile and run the program.

[Kevin_D_Intel]

Glad to hear that.

I perhaps should have been clearer in my earlier reply that while the OpenMP 4.0 target directives produce warnings when compiling with -mmic, those do not preclude building and running the small program natively on the coprocessor if desired. The target directives support offloading code to attached devices and thus are not applicable in native mode so those are ignored and produce the warnings shown; however, the code can still be compiled and run natively.
