Ah! I think I see the problem: the pTask->teb->cur_stack points to the
16-bit stack *after* the complete 16->32 thunking stack frame was pushed.
The stackmin/stackbottom fields, however, are supposed to contain the
stack pointer at the point of *call* to InitTask ...
Could you try with:
pinstance->stackmin = OFFSETOF(pTask->teb->cur_stack) + sizeof(STACK16FRAME);
pinstance->stackbottom = pinstance->stackmin;
(alternatively: SP_reg(context) + 4, but this should always be the
same value ... )
