Might be possible, but will cause troubles as the spec says:
"The error code is pushed on the stack as a doubleword or word
(depending on the default interrupt, trap, or task gate size)."
My guess is that this is an error and that the 32-bitness of a TSS
only refers to the format of the TSS, and has nothing to do with the
code that actually runs. I'll ask Intel about it. Meanwhile this can
be applied, if there's a problem with 16-bit exception handlers
running through a 32-bit task referenced by a task gate in the IDT, it
can be fixed later.
I meant, after Gleb's concerns are addressed.
