Regression: Updated to Qt 5.5.1 and QtCreator 3.5.1 today, breakpoints no longer work

[philipp]

Breakpoints were working fine before the update.
I updated to 5.5.1 (qt-opensource-mac-x64-clang-5.5.1) and QtCreator 3.5.1.
I'm using clang and lldb from Xcode 7:
$ clang --version
Apple LLVM version 7.0.0 (clang-700.0.72)
Target: x86_64-apple-darwin15.0.0
Thread model: posix
$ lldb --version
lldb-340.4.70
$ which lldb
/usr/bin/lldb

I have added the new Qt Version in QtCreator, changed the "Desktop" Kit to use the new Qtversion, deleted the .qmake.stash file in my source folder, made a make distclean, and rebuild using Qt 5.5.1.

Now when I start debugging with Cmd+Y and click a line it doesn't resolve the breakpoint to an address, so the breakpoint doesn't work. This is what it looks like when I hover over the breakpoint: http://imgur.com/OLhD6Ad

As it worked this morning before I updated, this is a regression introduced by either Qt 5.5.1 or Qt Creator 3.5.1
