Hi Oliver,

Thanks for your response, but please read again the command line I stated
in my first mail:

ml64 /Fo path/to/obj/file.obj /c path/to/source/jump_x86_64_ms_pe_masm.asm

Please note that this already *is* the 64bit MASM executable as stated in
the documentation. And using MASM64 leads to the aforementioned errors.
The error messages were as follows:

1>------ Erstellen gestartet: Projekt: boost, Konfiguration: Debug x64
1> Microsoft (R) Macro Assembler (x64) Version 14.00.23506.0
1> Copyright (C) Microsoft Corporation. All rights reserved.
1> Assembling:
1>: error A2008 : syntax error : FRAME
1>CUSTOMBUILD : warning A4020: directive ignored outside a procedure
1>CUSTOMBUILD : fatal error A1010: unmatched block nesting : jump_fcontext

So again the questions:

a) Is this the correct asm file for Visual Studio, x64 architecture?
b) If yes, where do those error messages come from? It's the same source
file, the same build tool, the correct invocation parameters, and no
includes or configuration referenced from that ASM file - should result in
the same object file, shouldn't it?

For reference: the 32bit version builds and links fine. Command line for
32bit is:

ml /Fo path/to/obj/file.obj /c path/to/source/jump_i386_ms_pe_masm.asm

I will not use bjam, as stated before: it does not allow the necessary
fine control over the compiler settings, e.g. the compiler choice v140 vs.
v140_xp. Ignoring this will build just fine but leads to rare crashes
which unfortunately do NOT happen on systems with debugging capabilities
but only on some client systems with *days* of response time. This is not
fun. So please, do not discuss the environment. Discuss the actual issue
at hand instead.

Thanks again.

Bye, Thomas
