Visual C++ 2005 upgrade problems

[freudj76]

Hi,
Currently, I am working on converting C++ applications written with C++ 6.0
to C++ 2005. I can compile the applications fine after slight modifications
but when I run applications, I am getting two different types of errors.

1 - The application failed to initialize properly (0xc0000005). Click OK to
terminate the application

2 - R6031. Attempt to initialize the CRT more than once. This indicates a
bug in your application

Some facts:

- Neither of the errors are due to missing dependencies. (I can verify this
by using dependencywalker)
- All the apps that crash are unmanaged dll's, and are not compiled with the
CLR option.
- Their C++ 6.0 versions run just fine.
-All underlying dll's have been compiled with VS 2005 as well, without the
CLR option

Any ideas will be appreciated.

There is a huge difference between those 2 compilers (almost 10 years) so it
is perfectly possible that code worked perfectly in VC6, but no longer in
VC2005. At least, this can happen if the original program uses behavior that
is undefined at some point.
The best thing to do is to step through your program and see where the crash
happens.
