[ros-diffs] [hyperion] 13140: Temporary hack to make ntoskrnl stop crashing - an user-mode pointer (in the EBP register) was being dereferenced without any check

Temporary hack to make ntoskrnl stop crashing - an user-mode pointer (in
the EBP register) was being dereferenced without any check
Since I don't know what this is for, I'm disabling it for now - it works
for people reporting the crash, and it apparently only breaks GDB
support. Alex, this should be your baby, please have a look
