MASM 10 needed.

[KeepingRealBusy]

Attached is a zip of a masm test I recently made. I am running MASM 9.0 from
Visual Studio 2008. When I tried to add the /SG option to the ML command line, I
encountered a MASM Internal Error. I was wondering if anyone had a copy of MASM
10.0 to try to assemble and execute this code and see if it also has the same
problems.

If you want to try, unzip the masmtst.zip file, and execute dotest.bat. This
will execute makeit.bat (make sure ML and LINK are in the path or change this to
a correct path for your system) and then it executes chkdata.exe. There is only
one API call in the program: ExitProcess.

Oh, by the way, you'll love the source code!

There are two assemblies, a chkdata.asm and a makedata.asm (identical code)
which include head.pkg, main.pkg, and test.pkg. The only difference is that
makedata.asm is assembled with the /SG option and fails, chkdata.asm assembles
correctly and executes correctly. There is no program output, just INT 3 traps
to detect incorrect execution.

There are other MASM errors as well. When the makedata.asm assembly fails, MASM
does not exit with an error code and so LINK tries to link a non-existant (null)
object and it too fails.
