PCD: Multiple Compilation Units

Is there any limit in number of units.

I have a project with 13 units and it's working fine. When I add a 14th unit I got compiler error 112, "Function used but not defined:"

If I remove a previous used unit (so it only will bee 13 units again) and comment all functions to the removed unit, it works to compile and link the project.

Anyone has any ideas?

I forgot to tell I have PCD compiler version 4.112.

I seems to me, that the multiple compilation units feature is a CCS C addon to give the look and feel of regular compiler and linker operation rather than a way to improve the actual compiler performance. Because it hasn't been working correctly with previous PCD versions, I wasn't motivated to try it again.

But what you report sounds clearly like a bug.
