This is the problem line - under DPMI in V1.x and always under V2.x there is
a fixed stack size, which defaults to 256K.  In this case your automatic
data is 256K, overruns the stack, and then the return EIP gets trashed by
some other data.

Either stubedit your image to increase the stack, or make the data static.

Here in the register information, it clearly says stack fault.  
The ESP is way too large.
