Problem with 11/785 running 4.3 BSD

[jp@ATRP.MEDIA.MIT.EDU (Jean-Pierre Schott)]

I am trying to build kcl for a Vax 11/785 running 4.3 BSD from the sources 
(ftped 11/16/87) from rascal and I receive a memory fault when I am trying to
build a saved_kcl. It occures during the save_system phase. Here is the
backtrace (I recompiled main.c unixsave.c with -g to use gdb)

gdb -q raw_kcl core

(gdb) p _iob[64]
$5 = 195065583
(gdb) p &_iob[64]
$6 = (long *) 0x41

As shown, the file pointer p is totally invalid. Any ideas or pointers would
be appreciated.
