the FPC compiler/runtime was the culprit. See issue 
The overflow is thrown in procedure edge_prep, module 329. Here is the 
statement from mf.p:

The int type cast is needed because of another error in the FPC 
compiler. (issue 37876)

But otherwise, I am quite satisfied with the Free Pascal Compiler.

Thanks for your replies,
