 I can't reproduce the problem with true too ... but i see this one :
 
 njoly@raya [tmp/sh]> cat sample.sh 
 #! /bin/sh
 echo "$#>>$@<<"
 njoly@raya [tmp/sh]> chmod +x sample.sh 
 
 njoly@raya [tmp/sh]> uname -a
 NetBSD raya.lan 7.99.1 NetBSD 7.99.1 (RAYA) #0: Tue Oct 21 23:31:13 CEST 2014  njoly%raya.lan@localhost:/local/src/NetBSD/obj.amd64/sys/arch/amd64/compile/RAYA amd64
 
 work on amd64 native :
 
 njoly@raya [tmp/sh]> ./sample.sh 1 2 3
 3>>1 2 3<<
 njoly@raya [tmp/sh]> sh ./sample.sh 1 2 3
 3>>1 2 3<<
 
 fail on amd64 compat netbsd32 chroot :
 
 njoly@raya [netbsd32:sh]> ./sample.sh 1 2 3
 2>>2 3<<
 njoly@raya [netbsd32:sh]> sh ./sample.sh 1 2 3
 3>>1 2 3<<
