Description

I have 2 dummy projects, one has "Generics.Collections" in its uses, another has nothing in its uses, and when I trace through the functions, and look in the CPU window, some function calls are renamed to "Generics + $441358" instead of being called by the name of my functions.

Steps to Reproduce:

Look in the attached ZIP.
To see the problem, put a breakpoint on "Test;" in the DPR file (line 98).
When breakpoint occurs, look in the CPU Window.

Variant1 Project (with Generics.Collections in uses) says this:

Project1.dpr.98: Test;
00444324 E84BD0FFFF       call Generics + $441374

Whereas Variant2 Project (with no uses section) says this:
Project1.dpr.96: Test;
004050C4 E867F5FFFF       call Test

Other differences, Variant1:
Project1.dpr.90: begin
00404630 53               push ebx
Project1.dpr.91: for I:=1 to 10 do
00404631 BB01000000       mov ebx,$00000001
Project1.dpr.92: WriteInt(I);
00404636 8BC3             mov eax,ebx
00404638 E8D7FFFFFF       call WriteInt
0040463D 43               inc ebx
Project1.dpr.91: for I:=1 to 10 do
0040463E 83FB0B           cmp ebx,$0b
00404641 75F3             jnz $00404636
Project1.dpr.93: end;
00404643 5B               pop ebx
00404644 C3               ret

Variant2:
Project1.dpr.92: begin
00441374 53               push ebx
Project1.dpr.93: for I:=1 to 10 do
00441375 BB01000000       mov ebx,$00000001
Project1.dpr.94: WriteInt(I);
0044137A 8BC3             mov eax,ebx
0044137C E8D7FFFFFF       call Generics + $441358
00441381 43               inc ebx
Project1.dpr.93: for I:=1 to 10 do
00441382 83FB0B           cmp ebx,$0b
00441385 75F3             jnz $0044137a
Project1.dpr.95: end;
00441387 5B               pop ebx
00441388 C3               ret
