linkage failure "_ZSt20__throw_length_errorPKc" when generating entry table.

[sharronliu]

When using OpenMP offload to accelerate my source codes, the module creation failed with a message "unresolved external symbol _ZSt20__throw_length_errorPKc". Could you suggest which library shall be linked, and how to tell the backend to link such library at runtime? Thanks.

The linkage error was found with either OPENCL or LEVEL0 backend.

OPENCL message: error : unresolved external symbol _ZSt20__throw_length_errorPKc at offset 396 in instructions segment #0 (aka kernel : __omp_offloading_10302_c20099__ZN3pcl29GreedyProjectionTriangulationINS_11PointNormalEE19reconstructPolygonsERSt6vectorINS_8VerticesESaIS4_EE_l359)
