I can imagine that it's difficult for you to debug something you cannot=20
reproduce. Just a remark I don't have 64-bits but a 32 so the problem is no=
t=20
comming because of the plateforme.

Yes it's doing the trick., I don't have anymore the problem. Thank you very=
=20
much. I have now the same result than you with the test I produce before.

just the classic one:

cc1plus: warning: command line option "-Wstrict-prototypes" is valid for=20
Ada/C/ObjC but not for C++

Thank you very much.
