SYMPTOMS

more of data to be declared in a segment. However, the linker will

be unable to link the object module produced. The linker will

generate the following error:

fatal error L1103: attempt to access data outside segment bounds

STATUS

Microsoft has confirmed this to be a problem in MASM version 5.0.

This problem was corrected in MASM version 5.0a.
