[Sander van Veen <sandervv+launchpad@xxxxxxxxx>]

The test case provided compiles successfully for me. I think that the
failure is caused by an incorrectly built standard library.

I've attached a build script that I use internally to rebuild all
standard libraries. Note that this script does not install the binaries
and libraries to the path /opt/cheerp though. Can you check if your
build commands are similar to that script?

My first guess would be to check if -DCMAKE_CXX_FLAGS="${CXXFLAGS}
-nostdlib" is used for libcxx and -DCMAKE_CXX_FLAGS="${CXXFLAGS}
-nostdlib -frtti" for libcxxabi.
