[Regression] "LLVM ERROR: Do not know how to split the result of this operator!" in executing Ubuntu UI Toolkit tests on x86

[Timo Jyrinki]

With upgrade to LLVM 3.5, UITK tests start failing with LLVM error. This was reported earlier and the change to 3.5 reverted, but now 3.5 landed again.

So we're seeing errors like this:

To reproduce, simply bzr branch lp:ubuntu-ui-toolkit and run bzr bd which also executes the unit tests.

Status changed to 'Confirmed' because the bug affects multiple users.

Happened now on ubuntu-system-settings-online-accounts autopkgtests, preventing qtbase from moving from -proposed to -release:
