New InstallShield: no more DLLs

There are some strange things happening that I'm still astonished about. I decided just
to write them down again - perhaps it may help to discover the error of the linking
As you know, I made some trials with a statically linked DLL build with GHC4.08.1 and the
a) When leaving debug information as it is, everything works fine - in all environments I
tested it on (WinNT, Win95; VBA, Delphi, VB - I had no possibility to test it on Win2K
b) When STRIP-ping away the debug information, the DLL on all PCs I tried it on works
fine with VB and Delphi - but when using it in VBA, it on some PCs crashes when the DLL
is loaded (the loading happens automatically when calling a Haskell function for the
first time) - this also looks like a problem during DLL initialization, it seems as if
DllMain is not even entered.
Did you already try out a statically linked, stripped DLL on Win2K? Do you get the same
error? (If the origin of the error is the same DLL initialization problem as in the
linking problem with EXEs, it may be easier to handle in a hell of a single DLL ...)
Some more strange things occured with the small program we had with catchAllIO / the "hi"
I compiled it in both ways with and without the "-static" option and sent the EXE
binaries to Arjan van Ijzendoorn (who reported the error).
a) When running the EXEs on my PC (Win95), both the statically and the dynamically linked
EXE work well (output: "hi").
b) The same EXE on A.v.I.'s PC with Win2K produced the "famous" application error.
Do you have some idea what's wrong here?
