I have a program (unfinished) working with the bytecode compiler ... and doing a segv with the native compiler ! (I use a Mandrake 8.1 with only standard packages). Various machines reproduce the problem (including a Mandrake 7.1) Do you have some hint ? I attach a tar.gz, just type make tests/geo2o; tests/geo2o to observe the crash However, make tests/geo2; tests/geo2 works fine (same program) I am not sure where to post the bug report (so many part involved so I try this list) -- Christophe Raffalli Université de Savoie Batiment Le Chablais, bureau 21 73376 Le Bourget-du-Lac Cedex tél: (33) 4 79 75 81 03 fax: (33) 4 79 75 87 42 mail: Christophe.Raffalli@univ-savoie.fr www: http://www.lama.univ-savoie.fr/~RAFFALLI
