What is the output of “which gcc” when you are using gcc8 as “default”.
Even if it seems like there is a priority or linking problem with the gcc versions, that seems to be another issue.
At 64% it seems like the compile stops when referring to something related to Cuda

Are you trying to compile with cuda support?
What does these files contain:
> /tmp/cc0rnp9j.out
> /var/crash/_usr_lib_gcc_x86_64-linux-gnu_4.6_cc1plus.1005.crash
Maybe there are some clues in there.
