 When compiling a code with DMC I get the following message:

 Internal error: cod2 3692
 --- errorlevel 1

 I have looked on the Digital Mars website for clues as to the meaning of
 the code, but cannot find any.  The code successfully compiles with GCC
 GNU 4.1.1 and  MSVC++ 7.1.

 Any suggestions as to where to look within the code would be helpful and
 appreciated.

Attached is about as simple an example of the problem as I can get.  As 
noted in my original post, it compiles (and links and runs) successfully 
with GCC GNU 4.1.1 and MSVC++ 7.1 and compiles successfully with Comeau 
4.3.8 (using their online test tool).

When I run the code in its attached form I get the following compile 
time error message:

Internal error: cod1 1293
--- errorlevel 1

When class A is defined in separate source and header files, compiling 
the source file yields the error message I mentioned in my earlier post.

The compile command I am using is:

dmc -Ic:\dm\stlport\stlport TestInline.cpp

The problem seems to involve combinations of the use of inline, static, 
and std::pair.  I've seen this before and have work arounds, but that 
becomes cumbersome when dealing with existing library code (e.g., 
special versions of library code for use w/ DMC).

Thanks again for any help.

Hi

I think you've done an excellent job of paring it down for Walter's
purposes - i.e. to be able to replicate, identify and fix the bug - but
probably a little too much for the kind of workarounds I'm familiar with.
;-)

If Walter can get this fixed soonish, that's probably your best bet. If not,
or if you can't wait for a new beta, I'd be happy to take a look at
something a little more substantial. From what you've presented, several
things come to mind, but they may not be appropriate in the real code. FWIW:

 - use a custom template pair instead of std::pair
 - use a non-template pair instead of std::pair
 - use a static reference and a static ptr+auto_ptr, e.g.

    typedef std::pair<int, int>    pair_t;
    static std::auto_ptr<pair_t>   b_(new pair_t(1, 1));
    static pair_t                            &b = *b_.get();

    (Note: this has thread-safety implications.)

 - move the static into another function / scope, e.g. into a local
namespace

That's all I can think of right now. HTH

All good suggestions to be sure.  I've opted for the simplest change to 
the existing code: comment out the inline statement.  I'm hoping this 
change stands the least chance of breaking something else.
