I tried to run these tests on my laptop, but they did not fail :thinking:

[traversaro]

Are you using the system IPOPT?

[S-Dafarra]

Actually no, I installed it manually to use the HSL solvers.

[traversaro]

Then I think the issue is a use of non-initialized memory in the system version of IPOPT, similar to https://github.com/robotology/idyntree/issues/456 .

[S-Dafarra]

The strange thing is that some of them do not use Ipopt :thinking:

cc @GiulioRomualdi that is having similar problems in https://github.com/dic-iit/bipedal-locomotion-framework/runs/851685876 . If the non-initialized memory use of ipopt is harmless (that is not given, in https://github.com/robotology/idyntree/issues/456 that was not the case) we should suppress them with a valgrind suppression file as done in https://github.com/robotology/idyntree/blob/d5bbceab9e8ae52943b31199f6e024d12ff52159/cmake/valgrind-macos.supp and https://github.com/robotology/idyntree/blob/d5bbceab9e8ae52943b31199f6e024d12ff52159/cmake/iDynTreeOptions.cmake#L34 .

This was probably fixed upstream in Ubuntu (see https://github.com/robotology/idyntree/pull/760), closing.
