What am I missing at the C ++ exception checkpoints in Xcode 4.3?

I want to be able to specify a subset of all C ++ exceptions for Xcode (lldb) to break. It seems like this is supported in the user interface:

But for my life I can’t make it work. If I leave it set to the default “All C ++ Exceptions”, it works and every exception thrown causes a breakpoint. If I try to specify an exception by name, the breakpoint never starts.

Has anyone else had problems with this, or is this just my problem?

Despite the UI, lldb cannot set breakpoints for specific C ++ exceptions or incorrectly resolves this name.

std::underflow_error, , lldb breakpoint list, , std::underflow_error:

9: name = 'std::underflow_error', locations = 0 (pending)

, lldb std::underflow_error. ++ name mangling .

++, , __cxa_throw:

10: name = '__cxa_throw', locations = 1, resolved = 1

  10.1: where = libc++abi.dylib`__cxa_throw, address = 0x01cefa44, resolved, hit count = 0
