Subject: 0020951: EDF 1501 SMESH: Conversion linear/quadratic with medium nodes on geometry... 
X-Git-Tag: end_translate_resources_09Jul10~23
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=da13b7ebd3dc1816183f010099effa91221fc742;p=modules%2Fsmesh.git

0020951: EDF 1501 SMESH: Conversion linear/quadratic with medium nodes on geometry fails with GHS3D
 * Fix for usecase: open the atached study, convert Mesh_1 from
   quadratic, unassign GHS3D algo -> SIGSEGV. Reason is that the same
   SMDS_SpacePosition is shared by all nodes in different solids.
