These hacks seemed to work around the worst of the symbol-reading problems
for me.  There's still other problems on this platform, though.

I actually sent a message in gdb-patches ~10 days ago about these
errors. I explained what I understand the problem is, and was asking for
advice in order to implement a clean solution.

Yes, I'm sure:

$ grep -i alpha gdb/README
alpha-dec-osf5.1
alpha-dec-osf4.0e

Here's the entry in its entirety:

    alpha-dec-osf4.0e

    GDB 5.1 is known to have problems on this platform (encounters an
    internal error in the symbol table reader).

To clarify, CC='cc -DUSE_LDR_ROUTINES' produced the same results on
