------------------------------------------+-------------------------------
When given a C++ object file, GHCi panics saying that it can't find
standard C++ symbols the object file relies on. If foo.cc contains
{{{#!C++
#include <iostream>
extern "C"
void foo ()
{
std::cout << "bar";
}
}}}
and is compiled with
{{{
g++ -fPIC -c -o foo.o foo.cc
}}}
then
{{{
ghci foo.o -lstdc++
}}}
fails with
{{{
GHCi, version 7.8.2: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading object (static) foo.o ... ghc: panic! (the 'impossible' happened)
(GHC version 7.8.2 for x86_64-unknown-linux):

It makes no difference to add -L
