There is good chance that there is some configuration parameter to
enable old behaviour (to run programs like Poplog). Simply, ATM
we lack info. We do not know exact reason for fault. We do not
know if this is general 5.8 thing or (more likely) Fedora thing.
We do not know if this is really kernel change or say configuration
change that is somewhat tied to the kernel (say buch of configuration
changes with some dependent of kernel features).
To put it differently, most guesses about software problems are
wrong. Here there are several factors involved, so chance
of resolving problem without digging deeper is virtually 0.
A data point:
In a virtual machine running Ubuntu 20.04.1 LTS, which comes with kernel
5.4, Waldek's 64 bit system with the no-pie patch builds and both pop11
and xved start up normally.
When I upgrade the kernel to 5.8, build_pop0 immediately gives an error
<<<<<<< Access Violation: PC = 00000000007AB060, Addr = 00000000007AB060,
Code = 2 >>>>>>>
but carries on and produces a corepop. The corepop starts up with the
same error, repeated several times. It then works at least to the
extent of doing simple arithmetic, but trying to define and run a
factorial function gives the access violation.
So the problem under kernel 5.8 is not exclusively a Fedora one. It is
at least a problem with something that Fedora and Ubuntu have in common.
Selinux is not installed in the virtual machine.
