I am attempting to build a DLL with C run-time functions from the standard
and migration C Set/2 multi-threaded libraries. I have .DEF files for
building both the .LIB and .DLL files that reference the required run-time
functions for startup and those run-time functions that my apps reference.
My .DEF file for the building the DLL includes the following:

    library mylib initinstance terminstance
    data multiple nonshared readwrite loadoncall
    code loadoncall
    exports
    ...

I can build the DLL and link my two application programs with the LIB for
my DLL without any problems. I start my first program and it comes up fine.
If I do a PSTAT, it shows my DLL being used by the program. While my first
app is running, I try to start my second app. I get the system error dump
dialog complaining about a protection violation in my dll. Not only this
but if I attempt to stop my first app., it either:
    1. hangs itself
    2. closes its window but still does not terminate
    3. hangs the system
In any case, I am forced to reboot.

I have read chapter 15 of the C Set/2 User's guide on including C run-time
functions in an application DLL as well as looking at sample03 in the
compiler samples directory.

Has anyone been able to accomplish what I am attempting to do? After a couple
of days of reboots, its getting to be quite frustrating...
