Linux guest crashes if VboxAdditions are installed

[S.Pendl]

Installing guest additions on LinuxMint 19.3 and Debian 10 results in a crash on startup of the VM. The vboxadd.service will not start. If the guest additions are removed the guest starts successfully.

I seem to be having a similar problem -- Windows 10 host, Fedora guest, VirtualBox version 6.1.10 r138149 (Qt 5.6.2), identical error message except for instruction address (but with same offset into VBoxDD.dll), same failing memory address (0x00...068), somewhat different stack:

I'll be happy to create a new ticket if necessary.

This looks like a null pointer dereferencing bug which has been solved quite recently but could not made to latest release. Current work around is to change the vm setting and use vmsvga graphics adapter. Please comment if the problem persist even when vm is configured to use vmsvga. Thanks.
