Re: [eigen] Uninitialized memory?

[Gael Guennebaud <gael.guennebaud@xxxxxxxxx>]

Actually, this warning has to be expected because we are prefetching data for the next loop iteration, but this last un-initialized data will never be used. Valgrind does not trigger a warning because un-initialized warnings are triggered only when the data is actually used.

Hi,

can you first try if the unit-tests sparselu_1...4 generate the same warning(s)? If not, could you provide a minimal example (i.e., including generation of a matrix)?

For the unit-tests I don't get corresponding warnings (under Linux/gcc, running with valgrind).
