Mark,
The current mainline gdb fails for ia64 linux due to an assertion in deprecated_select_gdbarch_hack(). I noticed you added this code recently. I have attached a scripted session with set debug arch 1. Can you verify if the debug messages indicate any unanticipated path through your code? I am just trying to debug a simple "hello world" program.
I noticed it too. The gdb_assert() in deprecated_select_gdbarch_hack() is faulty because gdbarch_update_p() does not necessarily change the current gdbarch to the one passed to deprecated_select_gdbarch_hack(). It can leave the gdbarch unchanged if it's semantically equivalent to the one asked to change to. Removal of the faulty gdb_assert() should do the trick.
