NT VDM Illegal instruction during C51 build

I'm using the 'Continuus' version control software and building from within this environment using
'object make'to call the C51 compiler v5.50.

I have a problem that half way through the build, windows (NT4.0) pops up an error
dialog which reads :

"16 bit MS-DOS Subsystem"
"C:\WINNT\system\cmd.exe"
"The NTVDM CPU has encountered an illegal instruction."
"CS:fe2e IP:010a OP:8f 9f 8e ad 24"

Building on a different machine doesn't produce the problem.
Building under Nmake doesn't produce the problem.

I don't know whether the problem is with the compiler, the make utility or Windows (NT4). Can anyone suggest
anything?

  • CMD.EXE program and that's not a part of the Keil installation. Is it a part of NT?

    Yes, CMD.EXE is the NT command shell (what most people think of as a DOS box). It is a full 32-bit replacement for the command.com shell which you can still use in NT if cmd.exe is troublesome.
