Some commands of current (after Feb 4, 2006) not work, hang-up.
I use 4.99.1-kernel and 3.99.15-userland(at Jan, 2006), this works well.
However the userland after Feb 4,2006 are not well.
Some important commands don't work, it hangups.
# /bin/ssh -V
# gdb /bin/sleep

This GDB was configured as "shle--netbsdelf"...(no debugging symbols found)...
Starting program: /bin/sleep
(no debugging symbols found)...(no debugging symbols found)...
**** ((( no return while very long time. Hang-up. Hit Interrupt ))) ****
^C(no debugging symbols found)...
Program received signal SIGINT, Interrupt.
0x00400ccc in frame_dummy ()
#0 0x00400ccc in frame_dummy ()
#1 0x00400824 in init_fallthru ()
#2 0x7fffdd1c in ?? ()
******** ((( no return again ))) ********
Strangely,　When using 'stepi' once, this works normally.
0x00400cce in frame_dummy ()
usage: sleep seconds
Program exited with code 01.
For more information,
When build userland by GCC 3.3.x (not GCC4), this problem occurs with other commands, for example, /sbin/mknod, /usr/bin/tset.
However, /bin/sleep works well. I don't know why.
I think the cause of this problem is not GCC4.
and I checkout with cvs co -Dxxxx and build some userland.
2006.02.04.00.00.00 not work. some commands (Ex./usr/bin/tset) hang-up.
It seems that this strange problem occurs after imported binutils 2.16.1.
And this problem does not occur on NetBSD/hpcsh with Jornada690 (SH3), it works well.
I think this occurs with SH4 CPUs only.
Use userland before Feb, 2006 (Befor import binutils 2.16.1).
Extracted 4.99.1-userland to /altroot/, then chroot to here.
