Please try to use gcc version 1.27 for fix it with following patches.

1. Tieman's patch in prep:/u/emacs/g++.tar-1.27.0.Z
2. my modification for Tieman's patch in
   Sun-4 running Sys4-3.2_REV2(about 10 K byte in context diff format.
   If you wish to try this, please mail me.)
   This problem is cased in diffirect function call protocol
   between gcc-1.27(also gcc-1.30) and standard sun cc as following.

* call instruction problem.
<cc>
call .ptr_call,1  # second args is # of args. adr is in %g1.
nop             # %o0 arg1, %o1 arg2,..

<gcc>
call %o1,0      # %o0 arg1, %o1 arg2,.. %on arg(n+1), %o(n+1) call addr
nop             # first arg is %o(n+1)
