--- Comment #14 from Alexios Zavras (zvr) <zvr+gcc at zvr dot gr> ---
I can confirm this bug also in gcc-9.3.0, gcc-10.1.0 and gcc-10.2.0.
To recap: if the system has a libiconv installed, the generated and installed
libstdc++.so depends on it.
However the compiler, when using it when compiling a C++ program, does not link
libiconv, resulting in an error:
$ g++ foo.cc
/usr/local/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld:
