A short script to reproduce this (sorry it not to easy to reproduce without the exact code, I did at one point get to the situation where adding a extra space in the white space area solved this!), but I suspect it is that the machine is running low on memory or something.... http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/phpmole-ide/phpmole/tools/uml_generator.class?rev=1.2&content-type=text/vnd.viewcvs-markup http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/phpmole-ide/phpmole/tools/uml_dia.xml.php?rev=1.1&content-type=text/vnd.viewcvs-markup -- just use it do do a large number of files. eg. php uml_generator.class /usr/local/php/pear/ Possible reasons that I could think of: -the tokenizer extension (which may be leaking memory) -somewhere not exiting if no memory can be allocated and then emalloc / malloc being called again. Configuration on this machine (4.2.0RC2), also reproduced with 4.2 release version './configure' '--prefix=/usr' '--without-mysql' '--with-config-file-path=/etc/php4/cgi/' '--enable-dba' '--with-db2' and tokenizer as a dl'd module Backtrace Program received signal SIGSEGV, Segmentation fault. 0x4014db2b in malloc () from /lib/libc.so.6 (gdb) bt #0 0x4014db2b in malloc () from /lib/libc.so.6 #1 0x4014d1e4 in malloc () from /lib/libc.so.6 #2 0x80c4c5c in _emalloc (size=35) at zend_alloc.c:165 #3 0x80d4b1a in zend_hash_index_update_or_next_insert (ht=0x817ae9c, h=207, pData=0xbfffda28, nDataSize=4, pDest=0x0, flag=4) at zend_hash.c:404 #4 0x80d303a in add_next_index_stringl (arg=0x8326d64, str=0x8268c08 ")", length=1, duplicate=1) at zend_API.c:847 #5 0x401ffc61 in tokenize () from /usr/lib/php4/cgi/tokenizer.so #6 0x402005ac in zif_token_get_all () from /usr/lib/php4/cgi/tokenizer.so #7 0x80eb4b0 in execute (op_array=0x816631c) at ./zend_execute.c:1598 #8 0x80eb679 in execute (op_array=0x8166a84) at ./zend_execute.c:1638 #9 0x80eb679 in execute (op_array=0x816004c) at ./zend_execute.c:1638 #10 0x80d19e8 in zend_execute_scripts (type=8, retval=0x0, file_count=3) at zend.c:810 #11 0x805e1dd in php_execute_script (primary_file=0xbffffb98) at main.c:1381 #12 0x805c0ac in main (argc=3, argv=0xbffffc14) at cgi_main.c:785 #13 0x400f86cf in __libc_start_main () from /lib/libc.so.6 PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

OK, Got a nice simple test case - I'm pretty certain its the tokenizer code, Andrei :) -- theres not category for tokenizer yet! :) test script as follows (modify the directory to point at pear).. <? dl('tokenizer.so'); class test { function testing($f) { if (!preg_match('/\.(php|class)$/',$f)) return; echo "$f\n"; $this->data =& token_get_all($f); } function recurse($dir) { $dh = opendir($dir); while (($f = readdir($dh)) !== FALSE) { if ($f{0} == ".") continue; $fn = "{$dir}/{$f}"; if (is_dir($fn)) { $this->recurse($fn); continue; } // assume its a file $this->testing($fn); } } } $t = new test; // change this to your pear directory. $t->recurse('/usr/lib/php'); ?>
