Hi,
I am trying to trace down the std::vector issue and stumbled over the following.
In HouseholderQR line 220, applyHouseholderOnTheLeft(...) is called
with this raw pointer
&m_temp.coeffRef(k+1)
which is mapped as
Map<typename ei_plain_row_type<PlainObject>::type> tmp(workspace,cols());
and results in unaligned data because even if m_temp is aligned,
m_temp.getData()+1 is not necessarily.
How do we fix this? This does not help - I always thought it were
affecting the Flags property
Map<typename ei_plain_row_type<PlainObject>::type, Unaligned>
tmp(workspace,cols());
