Hi Dominique,
A long time ago Paul sent me the following patch that fixes all three submodule ICEs in pr69498
Got any more patches like that? If so, could you maybe attach them to the relevant PRs? Even if such patches should turn out not to be perfect, they could still help. Regarding the patch: I think it makes sense to fix the problem that Nicolas discovered (the problem on freeing caused by the mismatch between symtree and symbol name), even if the error is no longer exposed due to the other patch. Regards Thomas
