Dear Hrvoje,

Description:
sample utility run in stressedFoam/plateHole case crashes after eating up all the available system memory.

Solver/Application:
the sample utility

Source file:
src/OpenFOAM/meshes/primitiveShapes/triangle/intersection.[CH]

Testcase:
tutorials/stressedFoam/plateHole

Platform:
openSUSE 10.3 x86_64 + both of the system gcc and gcc-4.2.2 built following buildInstructions.txt of OpenFOAM-1.4.1-dev

Version:
OpenFOAM-1.4.1-dev revision 393

Notes:
It appears that at least the tested gcc versions do not prefer the syntax
const_cast<scalar&>(planarTol_) = t;
to override the const attribute of a scalar variable planarTol_ in intersection::setPlanarTol(), despite this line does not result in any errors. Thus
scalar oldTol = intersection::setPlanarTol(0.0);
in octreeDataFace::intersects() is not properly executed, which leads to misdetection of intersection points.

The problem went away simply giving up declaring planarTol_ as constant as attached. I'm not sure if this is the best fix, but attaching for clarification of the fix that worked for me.
planarTolFix.diff

This problem does not exist in OpenCFD versions since planarTol_ is not declared as constant.

Best regards,
Takuya
