I'm trying to get GNU Emacs working correctly on a Interactive Unix
3.2 rel 2.2.1, using the job control feature.
Everything is running ok, and when I hit ^Z it stops correctly
returning me to the shell (bash 1.08 of course ;-)). But when I enter
the "fg" command, it core dumps, telling me "Segmentation fault". I
tried almost everything...
I'm using (of course again!) gcc 1.39 with "-posix" option: looking at
how gcc behaves with this option, I also initialized STARTFILES with
"pre-crt0.o /lib/crtp0.o". I tried crtp1.o too, but then "temacs" told
me "POSIX not supported"!!!
As a secondary question, what's the diffs beetween these two C startup
files (crtp0 and crtp1)??
I analyzed the core file with gdb, and it seems to me that when Emacs
reenter from ^Z, some variables get corrupted; eg, the first few lines
of the gdb "bt" command are:
#0 0xa4af in move_cursor (row=88161763, col=0) ...
#1 ... in reset_sys_modes()
#2 ... in fatal_error_signal (sig=11)
#3 ... in _sigreturn()
#4 ... in Fsignal (sig=21183740, data=88292276)
#5 ... in memory_full ()
#6 ... in xmalloc (size=88161764)
and so on. I was wondering about those large numbers...
I've modified s-386ix.h in the following manner:
#undef NOMULTIPLEJOBS
#define HAVE_PTYS
#define SYSV_PTYS
#define USG_JOBCTRL
#define HAVE_SOCKETS
A friends of mine told me to disable HAVE_SOCKETS, but the same
problem appeared...
Hints?
Thanx a lot, and my apologies for the cross-posting, but I do not
receive (yet... i hope ;-) gnu.*
