Compilation error with intel compiler

With meep-1.19 Intel compiler stops with following:

This error was inintroduced after meep-1.18.
I tried versions intel-2017.2.174 and intel-2019.0.117 with -std=c++11 option.

Several of the emitted warnings indicate that the compiler is not actually in C++11 mode.
How did you configure the build?
Furthermore, this post indicates that there are likely problems with the GCC libraries and headers used by the Intel compiler in your installation.

The switch "-std=c++11" was definitely added to CFLAGS and CXXFLAGS before running configure script. After digging I have found that CXXFLAGS inside Makefiles was set to just "-O3", probably from mpic++ installation (mvapich2). On editing Makefile inside src subdirectory, the compilation of meep 1.19 stopped here:
