It is difficult to supply sample code since the segfault depends at least on the following: * a successful call to odbc_pconnect('host:node','user', 'pass'); if odbc_pconnect fails there is no segfault * some (included?) code before odbc_pconnect While trying to reduce the code i noticed, that include(_once?) is needed to trigger the problem. That's meant with "some _included_ code" in the sample below. * filename "/var/home/tho/oss/sbwi/bin/php -c /var/home/tho/oss/sbwi/conf -f /var/home/tho/oss/sbwi/dump1.php" cores while the similar code in "/var/home/tho/oss/sbwi/bin/php -c /var/home/tho/oss/sbwi/conf -f /var/home/tho/oss/sbwi/dump.php" does not core The code itself works fine. The segfault always happens after the last line. We are connecting to ADABAS using ODBC configure: ./configure\ --prefix=$(PREFIX)\ --with-adabas=$(adabas_dir)\ --with-openssl=$(PREFIX) \ --disable-session\ --with-db\ --without-gd\ --with-config-file-path=$(PREFIX)/conf Reproduce code: --------------- <? [...some _included_ code...] $dbhandle = @odbc_pconnect('host:node','user', 'pass'); exit; ?> Expected result: ---------------- no segfault :-) Actual result: -------------- (gdb) run -c /var/home/tho/oss/sbwi/conf -f /var/home/tho/oss/sbwi/dump1.php Starting program: /var/home/tho/oss/sbwi/bin/php -c /var/home/tho/oss/sbwi/conf -f /var/home/tho/oss/sbwi/dump1.php Program received signal SIGSEGV, Segmentation fault. zend_hash_index_find (ht=0x82cece0, h=7, pData=0xbffff3f8) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend_hash.c:967 967 if ((p->h == h) && (p->nKeyLength == 0)) { (gdb) bt #0 zend_hash_index_find (ht=0x82cece0, h=7, pData=0xbffff3f8) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend_hash.c:967 #1 0x081518af in _zend_list_find (id=7, type=0xbffff428) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend_list.c:70 #2 0x080a212d in _close_odbc_pconn (rsrc=0x83071a0) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/ext/odbc/php_odbc.c:250 #3 0x08151b1e in plist_entry_destructor (ptr=0x83071a0) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend_list.c:203 #4 0x0815091a in zend_hash_apply_deleter (ht=0x82ced08, p=0x8323cb0) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend_hash.c:611 #5 0x08150a5b in zend_hash_graceful_reverse_destroy (ht=0x82ced08) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend_hash.c:677 #6 0x08151bc2 in zend_destroy_rsrc_list (ht=0x82ced08) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend_list.c:233 #7 0x0814bfb3 in zend_shutdown () at /var/home/tho/oss/sbwi/src/software/php-4.3.8/Zend/zend.c:554 #8 0x081262fe in php_module_shutdown () at /var/home/tho/oss/sbwi/src/software/php-4.3.8/main/main.c:1286 #9 0x08164319 in main (argc=5, argv=0xbffff694) at /var/home/tho/oss/sbwi/src/software/php-4.3.8/sapi/cgi/cgi_main.c:1685 #10 0x401027ee in __libc_start_main () from /lib/libc.so.6 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30052&edit=1
