making gdb evaluate a multi-line or compound if statement all at once

Question

Up until I started using Arch linux a couple of weeks ago, gdb would evaluate multi-line if statements atomically. So for a condition like this:

39523   if ((RM != NULL) && 
39524       (RM->DefaultC != NULL) &&
39525       (MSched.RemapC != NULL) &&
39526       (RM->DefaultC->FType != mqftRouting) &&
39527       (RM->DefaultC != MSched.RemapC))
39528     {
...
...
39728     } /* END if ... */
39732   if (ClassFound != TRUE)
39733     {

The only thing I'd see in gdb (unless I explicitly did a list command) was the first line:

39523     if ((RM != NULL) && 
(gdb)

Now I'm seeing the following:

39523     if ((RM != NULL) && 
(gdb) 
39524         (RM->DefaultC != NULL) &&
(gdb) 
39523     if ((RM != NULL) && 
(gdb) 
39525         (MSched.RemapC != NULL) &&
(gdb) 
39523     if ((RM != NULL) && 
(gdb) 
39526         (RM->DefaultC->FType != mqftRouting) &&
(gdb) 
39523     if ((RM != NULL) && 
(gdb) 
39527         (RM->DefaultC != MSched.RemapC))
(gdb) 
39523     if ((RM != NULL) && 
(gdb) 
39732     if (ClassFound != TRUE)

I can see this kind of behavior being desirable, but I'd prefer to be able to configure it. Does anyone know if this is possible? I'm using gdb 6.7.1, built from source. I was using this exact version, built from the same source, on my Ubuntu system before I switched to Arch.

Edit: I see the same behavior when using gdb --tui
