Extra import symbol in debug build

[i.nixman@autistici.org]

hello,


I can successfully build the same C++ code using GCC-8.3.1 for Debug (-g 
-O0) and Release (-g -O2) build.
I can successfully debug the Release-executable on a remote host, but I 
can't debug the Debug-executable on a remote host, because the 
Debug-executable imports an extra symbol 
_ZNKSt9basic_iosIcSt11char_traitsIcEEcvbEv from libstdc++ which doesn't 
exist.

but I don't want to debug libstdc++, so I think I shouldn't install 
additional debug version of libstdc++.

it looks like a bug, or am I wrong?

another my question is, what should I do to get rid of that extra symbol 
in Debug build?




best!

ps
I can't update GCC nor libstdc++.
