FIX: Near Call Between Segments Within a Group May Fail (74532)

MORE INFORMATION

The sample program below illustrates this problem. It defines two segments that are defined in the same group. Calls are being made from different offsets in the file. All calls after offset 0FDh are made to incorrect addresses rather than being set up as relocatable calls.

The following is incorrect code generated for the procedure called Generic:

 00F8                           Generic proc    near
 00F8  E8 0000 R                        call    Simple
 00FB  E8 0000 R                        call    Simple
 00FE  E8 11B2                          call    Simple
 0101  E8 5200                          call    Simple
 0104  E8 11B2                          call    Simple
 0107  E8 11B2                          call    Simple
 010A  E8 0854                          call    Simple
 010D                           Generic endp
				

The correct code that should be generated would appear as follows:

 00F8                           Generic proc    near
 00F8  E8 0000 R                        call    Simple
 00FB  E8 0000 R                        call    Simple
 00FE  E8 0000 R                        call    Simple
 0101  E8 0000 R                        call    Simple
 0104  E8 0000 R                        call    Simple
 0107  E8 0000 R                        call    Simple
 010A  E8 0000 R                        call    Simple
 010D                           Generic endp
