Bug#176797: libstdc++5: GDB looks in the wrong place for libstdc++ headers
Package: libstdc++5
Version: 1:3.2.2-0pre5
Severity: important
When running my c++ program from inside gdb I get the following:
danielb@frodo:~/software/src/cvs/gsim/src/examples/mm1$ gdb .libs/mm1

Even making a symlink here does not fix things.

87 }
So then I just said the heck with it and did an apt-get install
libstdc++3 and libstdc++3-dev (because the headers for that version are
located in the above include path that it complains about) and tried to
run it. Note: this is the wrong version of libstdc++ my program is linked
with.

I think something funky may be going on with libstdc++. At any rate it makes
debugging some c++ programs impossible. It wold be nice to be able to
use the latest libstdc++ when developing c++ apps and be able to run
them inside gdb.
Also, this may be hard to reproduce as it seems perhaps you need to make
a call into the locale templates, but I am not 100% sure of this.
