I don't know,  I noticed the same problem earlier. I think it's something 
related to fork or clone.

This command fails when installing kernel and modules:
qemu-system-sparc -kernel vmlinux-2.6.11+tcx -cdrom 
debian-30r4-sparc-binary-1.iso -hda hd -initrd debian-30r4-sparc.initrd 
-nographic -append 'cdrom ramdisk_size=16384 devfs=mount rw root=/dev/rd/0'

"There was a problem installing the Drivers from  
/instmnt/dists/woody/main/disks-sparc/current/sun4cdm/drivers.tgz"
and some errors in background.

Replace -cdrom with -hdb and the installer has no problems until installing 
libc6.

Much better, though a few spaces are still missing.
