I did all the steps above. The results are probably less helpful but
I'm still game to more instructions.
GDB was hitting its heuristic fence-post trying to load the core file
so I ran the sysinstall in the obj directory since it wasn't
stripped. This may be a bug in gdb that's hiding. Here is what I get
running the non-stripped version.
alpha# gdb -c

warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0x1201d6000
This warning occurs if you are debugging a function without any
symbols
(for example, in a stripped executable). In that case, you may wish
to
increase the size of the search with the `set heuristic-fence-post'
command.
Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
I did a quick search for tcflow but I think it's in some other
library that got linked in there.
