Comment 27 for bug 1396654

I am affected by this on Ubuntu 18.04 (Bionic).

The only workaround I have seen, is to build/rebuild the `perf` tool from the source package. This does not fix the problem for me on 18.04.

```
sudo apt-get install libiberty-dev binutils-dev
mkdir tmp
cd tmp
apt-get source linux-tools-4.15.0-39-generic
cd linux-4.15.0/
sudo apt-get build-dep linux-tools-4.15.0-39-generic
debuild --no-sign
```

Then, the newly built `debian/linux-tools-4.15.0-39/usr/lib/linux-tools-4.15.0-39/perf` still does not do any demangling of C++ symbols.

Am I doing something wrong, or is it a new kind of problem with a different solution on 18.04?

Any help will be greatly appreciated.
