Or you use the Obj module, or you do a stack overflow on some
architectures, or you access out of a string or array on some others.

Anyhow, if it is possible, try to compile your code with the bytecode
compiler and use the debugger that easily find this kind of problems.

Another simple way to localize the problem is to add a message at the
end of each compilation unit; for instance, as last line of the
implementation file foo.ml of module Foo, just write:

prerr_endline "Module Foo successfully initialized.";;

This way, you could normally see which module fails to initialized and
then you could find more easily why.

Hope this helps,
