__aeabi_unwind_cpp_pr1@GCC_3.5

["Bernhard R. Link" <brlink@debian.org>]

A large number of packages (I guess around 800-900)
generates the following warning on armel and armhf at build time:

dpkg-shlibdeps: warning: symbol __aeabi_unwind_cpp_pr1@GCC_3.5 used by
FILENAME found in none of the libraries.

and/or the warning

dpkg-shlibdeps: warning: FILENAME contains an unresolvable reference to
symbol __aeabi_unwind_cpp_pr1@GCC_3.5: it's probably a plugin.

Does anyone know the cause of this and how serious it is?
Does this need fixes or some whitelist in dpkg-shlibdeps to ignore this?

There are instances of this warnings from binaries generated with a pure
g++ --shared without anything about disabling standard libraries, so
I guess if this is a issue, it is a issue in gcc or one of the standard
libraries?
