I'm testing this.  Thanks for the feedback.

One early note is that this changes the expected output for this test:

FAIL: gdb.dwarf2/var-access.exp: verify re-initialized s2

Now it says:

print/d s2
$9 = {a = -65, b = 73, c = -25, d = 123}

but the test wants:

gdb_test "print/d s2"  " = \\{a = 191, b = 73, c = 231, d = 123\\}" \
    "verify re-initialized s2"
