BUG: H2INC Produces Garbage/GP Faults w/ Some Function Typedefs (72853)

SYMPTOMS

Under certain circumstances, the Microsoft C to MASM Include File Translator (H2INC) version 1.0 that ships with the Microsoft Macro Assembler (MASM) version 6.0 may generate invalid results for certain C include files with function typedefs. Under MS-DOS, the result may be garbage characters in the generated .INC file. Under OS/2, H2INC may cause a general protection violation (GP Fault).

The problem occurs in this file only when all the following conditions are true:

• Two consecutive typedefs in the file are used to define functions.
• The total argument count for the two typedefs is 10 or more.
• The last argument to the first function typedef is a far pointer.

/* Command line options needed: none
*/ 
typedef void Func1Def(int, int, int, int, void _far *);
// typedef void DummyFunc(int, int, int);  // Uncomment for workaround
typedef void Func2Def(int, int, int, int, int);

struct FuncStruct
{
   int arg1;
   Func1Def * Func1;
   Func2Def * Func2;
} FuncStruct;
