<?php
   $aa = is_array($HTTP_POST_VARS);
   phpinfo();
?>

That's all.
FreeBSD : exit signal Bus error (10)
Linux : SEGV

There is no crash if 
   $aa = is_array($HTTP_POST_VARS);
changes to
   $aa = is_array($HTTP_GET_VARS);

Environment(FreeBSD):
FreeBSD 2.2.8-RELEASE
Apache 1.3.14
  ./configure \
  --enable-module=most --enable-module=auth_db --disable-module=auth_dbm \
  --enable-shared=max
PHP 3.0.18 (not 3.0.17)
  ./configure \
  --with-apxs=(path) \
  --enable-sysvsem \
  --enable-sysvshm \
  --with-config-file-path=(path) \
  --without-gd
PostgreSQL 6.4.2

Environment(Linux):
Vine 2.0 based linux-2.2.17
Apache-1.3.12
  ./configure --enable-module=so --enable-module=rewrite
php-3.0.15-i18n-ja
  ./configure --with-pgsql --enable-track-vars \
  --with-apxs=/usr/local/apache/bin/apxs --enable-i18n \
  --enable-mbregex --enable-versioning
postgresql-7.0.3
  ./configure  --enable-multibyte=EUC_JP
rpm -qa|grep -w gd
  gd-1.8.3-0vl1
  gd-devel-1.8.3-0vl1
  gd-progs-1.8.3-0vl1
php3.ini is same as php3.ini-dist

It corruped at next of following line (functions/info.c)
if (_php3_hash_find(GLOBAL(active_symbol_table), "HTTP_POST_VARS", sizeof("HTTP_POST_VARS"), (void **) &data) != FAILURE) {

_php3_hash_find says the value is FOUND but ...
data->type says NOT IS_HASH
Why?

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
