Comment:

 Ouch. This bug has been biting me for a while now. How can optimization
 cause a segfault for {{{g.copy rast=rast1,rast2}}} but not for {{{g.copy
 vect=vect1,vect2}}} ? This sounds like a nasty bug to me.

 I have noticed this problem with the latest SVN on x86 and AMD platforms,
 using the standard compile options:

 {{{
 # options for opteron:
 export CFLAGS="-march=opteron -O2"
 export CXXFLAGS="-march=opteron -O2"
 #optimization for P4:
 export CFLAGS="-march=pentium4 -O2"
 export CXXFLAGS="-march=pentium4 -O2"
 }}}
