I am trying to compile and use the ZeroC Ice remoting library for armhf to
run on my RaPi 2. The compilation goes fine, but when running the test
suite I am getting a NullReferenceException on the pointer assignment in
the following code:
fixed(byte* p = _bytes[_position])
{
*((float*)p) =
Hi,
Mono sets up signal handlers in order to implement throwing null reference
exceptions. This means that some SIGSEGVs etc. get converted to
NullReferenceExceptions.

Hi,
arm might require aligned reads, i.e. 'p' should be 4 byte aligned in this
case.

That's a good point! Can you tell me where in the mono code that the
unaligned accesses are handled? I'd just like to confirm.
Thanks!

Yes, I can tell that the pointer is unaligned, I was wondering why I would
get a NullReferenceException for an unaligned access. I would assume that
mono sets up some handler or something that catches unaligned exceptions?
Maybe not?

Hi,
You can check whenever the pointer is aligned by converting it into an
int.

Could also cast to an IntPtr and check the Size property, which would
return the number of bytes in the pointer?

Might be misunderstanding the issue though.
