PUSH Imm32 Illegal with .286 ID Number: Q26831

5.00 MS-DOS buglist5.00

Problem:

MASM generates a warning for the following:

.286 PUSH imm32

However, an error should be generated because this instruction is illegal on the 286.

Response:

Microsoft has confirmed this to be a problem in Version 5.00. This problem was corrected in MASM Version 5.00a. Please contact Microsoft Product Support Services by calling (206) 646-5109 to obtain the MASM Version 5.00a update.
