[Spread-users] unaligned int access on sparc solaris

[drago.krznaric at se.transport.bombardier.com]

Hi all,

I just downloaded spread-4.0.0 and compiled it for sun sparc solaris.

Unfortunately, I got a bus error when starting spread daemon, caused by 
the following
macro in stdutil.c:

#  define stdhcode_sfh_get16bits(d) ( ((stduint32) *((const stduint8 *)(d) 
+ 1) << 8) | *(const stduint32 *)(d) )

It is the  '  *(const stduint32 *)(d)  ' that sparc doesn't like when d 
doesn't point to an aligned integer. 

For me it looks as if one tries to flip the bytes in a short (big endian 
to little endian), in which case the following
should do the same thing but without the bus error:

#  define stdhcode_sfh_get16bits(d) ( ((stduint32) *((const stduint8 *)(d) 
+ 1) << 8) |  (stduint32)*(const stduint8 *)(d)  )

Has anybody else done a similar change?
