I confirmed that #234691 is glibc bug, not mkisofs.
Sometimes pointers of inbuf/outbuf of iconv(inbuf, outbuf) is
unaligned (not 2 or 4 byte alignment), but glibc iconv routine for
UCS-2LE/UCS-2BE cannot handle such unaligned memory access. This
causes problems on some architectures which does not allow unaligned
memory access like sparc, hppa, alpha, and so on.
Generally kernels on such architectures recover automatically, but
linux/sparc sends process SIGBUS when it's trapped unaligned access
exception.
I've put the fix for the current debian-glibc cvs. This bug will be
fixed in 2.3.2.ds1-14. Now glibc and linux-kernel-headers packages
are RC bug free for releasing sarge!
