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!

Edit:
The fileNames testCase and even testCAse will also lead to this bug.
The issue could be related to #4355.
