Problem:

Looking at the header of a .EXE file, compiled with C Version 5.10
with the following

   cl foo.c

and linked with

   link /CP:1 /E foo;

EXEMOD shows that the value of the minimum allocation(para) is higher
than the value for maximum allocation(para).

The description of EXEMOD implies that this is not possible (Page 323
of the Microsoft "CodeView and Utilities, Microsoft Editor,
Mixed-Language Programming Guide" manual, under the description of
/MAX).

Response:

Under normal circumstances, the minimum allocation size cannot be
larger than the maximum allocation size. However, on Page 324 of the
Microsoft "CodeView and Utilities, Microsoft Editor, Mixed-Language
Programming Guide" manual, it states the following:

   If either the /MIN or the /STACK option is used, the value is
   CORRECTED as necessary to accommodate unpacking of the modified
   stack. The /MAX option operates as it would for unpacked files.

In other words, the minimum allocation value listed in a packed file
is corrected to allow for the unpacked stack space. Since the maximum
allocated value does not change for packed files, this COULD result in
the minimum value being much larger than the maximum value. Note that
this is the same whether the file is packed using the /E switch with
LINK, or separately with EXEPACK.
