Q61603: TEXT.C Can Cause a Protection Violation Under OS/2

Article: Q61603
Product(s): See article
Version(s): 6.00
Operating System(s): OS/2
Keyword(s): ENDUSER | buglist6.00 | mspl13_c

If the example file TEXT.C (obtained from the C Compiler version 6.00
online help) is compiled using the large memory model and the OS/2
protected mode libraries, the following operating system error may
occur:

   SYS1943: A program caused a protection violation.

To reproduce this problem, cut the example program out of the online
help and save it to a file named TEXT.C. Then compile with the
following command line:

   cl /AL /Zp text.c grtextp.lib

Upon invoking TEXT.EXE, the SYS1943 message will be displayed and the
program will exit.

Due to a problem with the _outtext() function, compiling this program
in large memory model produces the protection violation.

As a workaround, if you compile the program with the small memory
model (/AS), the program will run properly.

Microsoft has confirmed this to be a problem with the C Compiler
version 6.00. We are researching this problem and will post new
information here as it becomes available.
