New Comment:
I done some other tests with the latest snapshot (php4-20020206000).
If I put a set_time_limit(0) on the top of the script php doesn't crash
but it takes a long time to finish (~3 minutes on an athlon XP1800 with
512M); probably it is freeing memory a lot of memory.
If I put set_time_limit(10) the script crashes:
Starting program: /usr/local/bin/php test.php
OK!
Fatal error: Maximum execution time of 10 seconds exceeded in Unknown
on line 0
Unknown(0) : Fatal error - Maximum execution time of 10 seconds
exceeded
Program received signal SIGSEGV, Segmentation fault.

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)

Spoken too early, the bug is also present in 4.0.6, but the program
doesn'crash, it says Maximum execution time exceeded ) and hangs.
Killing the process with SIGABRT produces the following backtrace (got
from the core file)

I found a bug using php 4.1.1 on redhat linux 7.1
My script uses the xml_parse_into_struct to parse a large XML file (2
mb) and then inserts the contents into a mysql database.
The script hangs at the end, and after 30 seconds it exits with
<b>Fatal error</b>: Maximum execution time of 30 seconds exceeded in
<b>Unknown</b> on line <b>0</b><br>
Segmentation fault (core dumped)
The script is launched from the command line.
This is the backtrace of the core file
(gdb) bt

The script works fine with php 4.0.6
