Upgrading virtualbox with wrong gcc version

[flg]

I have several versions of gcc installed (4.4, 4.7 and 4.9). gcc links to 4.4 (it's my default). When upgrading the kernel (with apt upgrade), the dependency system correctly computes that it has to rebuild the virtualbox driver (vboxdrv). But doing so, it uses gcc 4.4. The compiled driver is incompatible with the kernel (as the kernel is compiled with gcc 4.9).

I had this error in dmesg: vboxdrv: Unknown symbol mcount (err 0)

So the update process fails (and correctly indicates that it has failed).

To fix the issues, I did this:
sudo sudo update-alternatives --config gcc
and selected gcc-4.9.

sudo apt remove virtualbox
sudo apt install virtualbox

And the problem was solved.

I guess the compilation of vboxdrv must check if it uses the same version of gcc that was used to build the kernel.

this might have happened with some old compilers, I guess now this isn't the case anymore (at least I never experienced this with gcc >= 4.8)
