Very strange error messages when filename contains "InnerOuter"

[Jan Kokert]

Hi I just wanted to create a ticket regarding inner/outer problems and provide a minimal example for that. But by doing this I observed another very strange bug: a simple model will not compile and will give many very strange error messages of the kind:

TestInnerOuterEqu.Top.o:testInnerOuterEqu.top.c:(.data+0x1a0):
undefined reference to `testInnerOuterEqu_top_function_equationsSynchronous'

Here is the code:

package TestInnerOuterEqu
  model Top
    Real a;    
    
  equation
    a = 1;
    
  end Top;

end TestInnerOuterEqu;

It seems that the filename will lead to the problem. Renaming the package to e.g. testInner or testOuter will solve the problem!!! This is totally weird!

The issue could be related to #4355.
