Re: CORBA_double on SGI

[Simon Britnell <simon britnell peace com>]

I think this is a problem with the size of the memory allocation header 
that ORBit prefixes to memory blocks it allocates.  The problem is that 
ORBit calls malloc to allocate (header_size+requested_size) bytes, sets 
values in the header and returns the pointer offset past the header.  If 
that offset is not a 64 bit boundary, the doubles don't fall on a 64 bit 
boundary and when the instruction is executed to fetch them, it 
generates a SEGV.  I have a patch for this which I didn't post because 
it added unnecessary padding in most cases.  I'll clean it up and post 
it within the next 24 hrs.
