I'm trying to boot October 6th -current kernel on my sun3/80.
It boots up to multi user mode, but only csh and tcsh does not
work so I cannot login.

The csh and libc binary is made from around June 10th
-current(1.3F?) source. These binaries work fine on
1.3G (around August 20th?) kernel.

I make csh binary with `cc -g' and old libc
(I don't make new libc yet), then gdb says:

Is there something wrong around sigreturn(), or my old binaries?
Oh, I'm using egcs. Is this wrong?
