The attached branch with the backported fix seems to indeed fix the
testcase. Can someone pick this up and sponsor it? I would also suggest
SRUing it to quantal as it possibly fixes bug 1067907.

@doko: Since

likely is caused by the same root cause, is it possible to backport that
fix, so that the next LibreOffice SRU is fixed with this?

work, so I don't see what can/should be fixed on the GCC side. Is there

Reproduction scenario: Note that the rand() stuff is needed, a sequence of 500
subsequent entries does not cut it (hash collisions needed to trigger the bug
maybe?).

Bjoern, we definitely should not be including two copies of boost in
main to work around this bug. Can you provide a minimal test case
showing the problem with the boost code, so we can work on getting that
fixed?

As per upstream bug:
Building LibreOffice with its internal boost version (1.44) evades the bug on
quantal. It works fine with boost 1.48 on precise, so its a regression.
