Bug description

Folks,

I wrote to Pierre.Weis@inria.fr, as mentioned at the top of
http://caml.inria.fr/FAQ/FAQ_DEBUTANT-eng.html but the message bounced.
Can anyone have a look at this? Thanks!

Regards,

Jens

Subject: bug during configuration of ocaml
Message-ID: 20030316165950.GA49272@schweikhardt.net
Mime-Version: 1.0

Cher Pierre,

I'm trying to compile the lang/ocaml port on FreeBSD 4.8-RC. The
configure script apparently runs a program to test wether stack overflow
can be detected.

Snippet from configure:
...
# Determine if system stack overflows can be detected

if test a = a; then
set -x
case "$arch,$model,$system" in
  i386,*,*)
	case "$host" in              # Check for FreeBSD 4.5 bug
	  *-*-freebsd*|*-*-openbsd*) check_pthread=yes ;;
	  *)                         check_pthread=no ;;
	esac
	if ./runtest -DTARGET_$arch -DSYS_$system stackov.c \
	&& test $check_pthread = no || cclibs="-pthread $cclibs" \
		   ./runtest -DTARGET_$arch -DSYS_$system stackov.c; then
	  echo "System stack overflow can be detected."
	  echo "#define HAS_STACK_OVERFLOW_DETECTION" >> s.h
	else
	  echo "Cannot detect system stack overflow."
	fi;;
  *)
	  echo "Cannot detect system stack overflow.";;
esac

The "tst" program run by ./runtest hangs indefinitely and eats all
available CPU. It can not be killed with TERM, HUP, INT or QUIT, but
only with kill -KILL.

I have traced the problem down to

cd /usr/ports/lang/ocaml/work/ocaml-3.06/config/auto-aux

cclibs=-pthread ./runtest -DTARGET_i386 -DSYS_bsd_elf stackov.c

The program runs fine without cclibs=-pthread
Could you have a look at this? Merci!

Regards,

Jens
