c++.windows.32-bits - coff2omf.exe produces wrong omf file - example.zip

coff2omf.exe produce omf file from coff input with some mistakes
I attached an example, where it is very clear to see.

Here the disassempled input from original (coff) obj file

text:00000156                 db 4, 7Fh dup(6), 5

==================================================================
The result of conversion to Omf is totally wrong!!!
