If "blockMesh" is executed in the tutorial $FOAM_TUTORIALS/basic/potentialFoam/cylinder using an OpenFOAM version compiled with the Intel compiler, the following error message will appear:

codeStreamTemplate.C(35): error: invalid line number

#line 0 "/path/to/system/blockMeshDict.#codeStream"

I tested this with Intel2018 and 2019 and OpenFOAM v1712 and v1812 on two different systems and the error happens with all instances where dynamicCode is used.

The generated code in cylinder/dynamicCode/_1c19e29ae18c779aa836a14631d6419f303e3d9d/codeStreamTemplate.C in line 35 reads:

#line 0 "/path/to/cylinder/system/blockMeshDict.#codeStream"

The Intel compiler complains about the "0". If instead "blockMesh" is run with an OpenFOAM version compiled with clang or gcc, the same code is generated but the compiler does not complain. A quick fix would be to remove the following line:
