Thanks for the note, Ulrich. Unfortunately, I have missed Jan's message about fails somehow. Moreover, I was in vacation for the last few weeks, so I read your message just now. I'll look at those tests and provide the fix.


Thanks,
Anton.

Yeah. I'm sorry about the delay. The patch is ok, please check it in.
Checked in.

Fedora 17 x86_64:
+FAIL: gdb.mi/mi-var-rtti.exp: list children of s.public in type_update_when_use_rtti
+FAIL: gdb.mi/mi-var-rtti.exp: list children of s.ptr (without RTTI) in type_update_when_use_rtti
+FAIL: gdb.mi/mi-var-rtti.exp: list children of s.ptr.public (without RTTI) in type_update_when_use_rtti

Yes, I'm seeing similar failures on a number of platforms (arm, spu, s390x).

The reason seems to be that the test case is attempting to display local
variables that are not yet initialized, and thus their contents are random.
For C++ objects, this includes a random vtable pointer ...

Now, this particular sub-test appears to do this deliberately; all the other
sub-tests only create the varobj *after* their corresponding objects were
initialized.  I'm not quite sure what exactly the test is supposed to be
testing, but I guess it ought to be done differently ...

Bye,
Ulrich
