source, output, clang commandline, temps
The attached code ( templateInt.cpp ), invoking a version of the later
std::invoke inside an omp target region crashes clang when compiled with the
command line:
clang++ -fopenmp -fopenmp=libomp -fopenmp-targets=x86_64-pc-linux-gnu
-stdlib=libc++ --save-temps -fopenmp=libomp -g -std=gnu++11 templateInt.cpp
It does compile with std=c++14, but it is c++11 compliant (note, that
BOOST_NO_CXX14_RETURN_TYPE_DEDUCTION is defined and thus trailing return types
are given for auto functions).
This crash looks similar to [1] but is different. Compiling the code crashing
example from [1] with the above commandline does succeed.
