Error while exe from shell! Please Help!

[pocahontas]

I can run all the
exe files
successfully from
main individually.
However, when I use
shell.exe to load
other files (b.exe,
long.exe), the
program crashes with
the following error:

Exception 13

Does anyone know
how to fix this
error? I've already
used memset() to
clear the allocated
memory for
userContext.

Thanks

Try initializing refCount to 0 even though we never use it, I think
thats how I fixed a similar problem...

The exception 13 should be fixed if you call Exit(code) in your
Sys_Exit() function.

I have been having the same problem with the exception 13. Does
anyone have any other ideas on how to fix it. Thanks.

Just a few more things you can check that messed me up initially.
Pointers in C are so much more irritating than in C++.
1. Make sure you use Free() on EVERYTHING allocated with Malloc(). And
you should be using Malloc() before memset().
2. Make sure your Sys_Spawn() function program is returning a positive
number. If not you may have pointer issues in your Spawn(char*, char*,
struct Kenrel_Thread**) function.
