Sorry for the late reply!

I got different results:

masm 6.15 + ms link: source files ok
masm 8.00 + ms link: source files empty
jwasm 2.08a + ms link: source files ok
jwasm 2.09pre + ms link: source files ok

I didn't test jwlink because I don't expect ollydbg to understand the debug info written by jwlink.

I noticed that in the previous post I used MS link from VC2003Toolkit ( v7.10.3077)
With MS link from VS2008 ( v9.00.30729.01) all 4 combinations are ok.
