Description:
During the decomposition of a blockMesh-generated Mesh with merged patch pairs, the decomposePar utility crashes and prints an error message "malloc(): memory corruption". This issue was previously reported here: http://www.cfd-online.com/OpenFOAM_D...es/1/1410.html

The fault seems to happen in the source file "domainDecomposition.C" (part of decomposePar) between line 125 and line 157 and is raised by multiple calls of the function "mark" (If calls of "mark" are commented out, no error is raised and the execution goes beyond this part of the program)

The error is linked to the point- and faceZones, which are created by blockMesh. If all pointZones, faceZones and cellZones are removed from the case, the error does not occur.

Solver/Application:
decomposePar

Source file:
domainDecomposition.C

Testcase:
an example mesh can be downloaded from here: http://palamedes.fms.uni-rostock.de/...s/testMesh.tgz (15MB)

Platform:
