Got a simple repro:
1. Open this VS2015 command prompt: VS2015 x86 x64 Cross Tools Command Prompt
2. Create a test.asm in this path: C:\asif\asif1\asif2\
.CODE
main PROC
mov eax,rax
mov ecx,rcx
RET
main ENDP
3. Run this ML64 command:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC>ml64 /c c:\asif\asif1\asif2\test.asm
Microsoft (R) Macro Assembler (x64) Version 14.00.24210.0

Assembling: c:\asif\asif1\asif2\test.asm
c:\asif\asif1\asif2\test.asm(7)e
c:\asif\asif1\asif2\test.asm(7) : error A2088:END directive required at end of f
il☺c:\asif\asif1\asif2\test.asm(4)e
c:\asif\asif1\asif2\test.asm(5)e
Notice these above errors are scrambled and bogus!
The odd thing is this command works below:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC>
ml64 /c c:\asif\asif1\test.asm
Microsoft (R) Macro Assembler (x64) Version 14.00.24210.0

Assembling: c:\asif\asif1\test.asm
c:\asif\asif1\test.asm(7) : error A2088:END directive required at end of file
c:\asif\asif1\test.asm(4) : error A2022:instruction operands must be the same size
c:\asif\asif1\test.asm(5) : error A2022:instruction operands must be the same size
It seems like a file path with many slashes "\" or path length confuses ML64.exe?
Also, the 32bit compiler ML.EXE produces scrambled results:

VS2008 & VS2012 seem okay, VS2013/15 are not!
