You just found a bug in valac, but let's see your output. For the
subclass you got :
> subclass - virtual
> interface - other virtual
> Segmentation fault
here I get this instead (using the tip of switch-to-gir branch, which is
based on 0.11.3):

So the second one is correct (i.e. has probably been fixed meanwhile).
However, the third one still fails (the abstract interface method
implemented as non-virtual method). Using gdb, I found out that it is an
infinite recursion problem and commenting out the line :
iface->abstract_function = (void (*)(Interface*)) interface_abstract_function;
in the generated code makes it work as expected (i.e. I get "class -
abstract"). So you just have found a bug (rather 2, but one is already
fixed).
It might be a good idea to test all combinations of
abstract/virtual/implemented as virtual/normally implemented, etc. with
latest vala and report exactly what works and what doesn't.
HTH,
Abderrahim
