The crash is created due to shell limits, as this creates 157/159M of memory in an instant.
$ ulimit -d
393216

$ php -d max_execution_time=900 -q -e ./crashtest.php

FATAL:  emalloc():  Unable to allocate 32 bytes
Segmentation fault (core dumped)


In a web environment it also kept 'unwinding' CPU time slowly - like 30 secs and only freed
5 megs:

  PID USERNAME PRI NICE  SIZE   RES STATE   TIME   WCPU    CPU COMMAND
18974 nobody    18    0  152M  157M sleep   1:25  0.00%  0.00% httpd


Only after a SIGHUP on Apache, the memory will be freed.
Tested with CVS/php4-200201050300.




PHP Version: 4.1.1
New Comment:

I have a testcase:

test.php:

<?
  @$data = implode("",file("export.xml"));
  $parser = xml_parser_create();
  xml_parser_set_option($parser,XML_OPTION_CASE_FOLDING,0);
  xml_parser_set_option($parser,XML_OPTION_SKIP_WHITE,1);
  xml_parse_into_struct($parser,$data,$values,$tags);
  xml_parser_free($parser);
  echo "OK!\n";
?>

The export.xml file is available on
http://www.libertyline.com/download/export.xml.bz2 (the compressed
version is only 3213 bytes)
