So likely clang is producing different output wrt debug information than
gcc. It might even use a different implementation of the standard
library. The "helpers" are very specific to a compiler and a standard
library implementation.  It is not to be expected that this "magically
works".

Maybe the library implementation has changed in the meantime.
Someone with a Mac in reach might want to double-check.

The ability to re-build Creator is easy to aquire: Run

   git clone git://gitorious.org/qt-creator/qt-creator.git
   cd qt-creator
   qmake -r
   make

in a shell. Creating LLDB support in a prebuild plugin is likely
to be a bit more work.
