It's 4 bytes, all right.

/home/mec/bin/gdb-611: PA-RISC1.1 shared executable dynamically linked -not stripped
a.out: PA-RISC2.0 shared executable dynamically linked -not stripped

(gdb-611) show architecture
The target architecture is set automatically (currently hppa1.0)

The funny thing is, gdb 6.1.1 "maint print registers" says that
r19 is 4 bytes long, but "info reg r19" has special code to print
all 8 bytes of it.

I'm still kinda dubious, but if it's okay with randolph that the
debugger quietly operates in 32-bit mode, it's okay with me.
I would do something like this:

gdb_test_multiple "info reg r19" "$name" {
-re "r19 deadbeefbadcadee ..." {
pass "$name (64 bit)"
}
-re "r19 "badcadee ..." {
pass "$name (32 bit)"
}
}
