I'll try to implement that. For sure, non-function symbols will show up
from time to time... However, in a typical ELF object file, there are
somewhat rare, while wrongly disassembled functions were the standard :)

I think vax-linux isn't yet a supported gdb target, but I'll try to get
NetBSD running on one of my /90 and have a test with it, too. The BSD
guys should have basically the same problems here...
Thanks again, JBG
