PASS: gcc (GCC) 4.7.1 20120504 (prerelease)
FAIL: gcc (GCC) 4.8.0 20120504 (experimental)
(I do not have it here to verify but apparently 4.8.0 20120503 PASSed.)
There are 338 GDB testsuite regressions due to it, one for all:
p acp->c1
-$9 = (A *) 0x0
-(gdb) PASS: gdb.cp/class2.exp: p acp->c1
+$9 = (struct A *) 0x0
+(gdb) FAIL: gdb.cp/class2.exp: p acp->c1
PASS:

<21e> seems to be excessive/redundant.
