This sounds really strange. Please do file a bug, we need to investigate this.
There were two really minor bugs fixed in the compiler in 4.3.2, neither of which could affect this (one would cause the compiler to crash and one caused it to emit an error on legal code). LLDB did change, but the changes are also very contained, focused on fixing the "ivar lookup" problem that many people experienced with the simulator and when debugging devices.
