How to repeat:
Try to compile MySQL Workbench on Ubuntu 16.04, satisfying dependencies like libssh by compiling and installing manually.

Hello Pablo, 
you need to have libssh with additional patch for libsshpp.hpp.

That patch was merged just yesterday. 
https://git.libssh.org/projects/libssh.git/commit/?id=5ea81166bf885d0fd5d4bb232fc22633f5aa...

Yeah, found this patch also in a mailing list, but the patch alone wasn't enough: you have to compile libssh directly from master.

I've been able to compile, install and execute MySQL Workbench 8.0.12 finally and it seems to work, but it gives a "free(): invalid pointer" only when trying to connect with a MySQL database (a RDMS connection seems to don't crash).

May it be related to the Connector/C++?

Please provide your cmake setup as also information which cpp connector are you using and what are the compiler flags.
