From: Operating system: Linux-2.6 / CentOS 5.8 PHP version: 5.3.11 Package: DBM/DBA related Bug Type: Bug Bug description:dba_fetch() segfaults with db-4.8
Description: ------------ When using dba_fetch with a db4 database a segfault is generated and php crashes. Important Notes: We use db48 rpm from ZeroC for IcePHP Support. At the time of testing we did not have the IcePHP.so loaded to ensure that it was not a conflict with that module. dba.so is linked against this db4 rpm: http://www.zeroc.com/download/Ice/3.4/rhel5/x86_64/db48-devel-4.8.30- 1ice.rhel5.x86_64.rpm [root@web2 ~]# ldd /usr/local/php/lib/php/extensions/no-debug-non-zts- 20090626/dba.so linux-vdso.so.1 => (0x00007fff62deb000) libdb-4.8.so => /usr/lib64/libdb-4.8.so (0x00002b024cad9000) libc.so.6 => /lib64/libc.so.6 (0x00002b024ce43000) libpthread.so.0 => /lib64/libpthread.so.0 (0x00002b024d19b000) /lib64/ld-linux-x86-64.so.2 (0x00002b024c6a3000) Test script: --------------- <?php $dbh = dba_open("/root/test.db","c","db4"); $str = sha1("this is a test"); $ret = dba_exists($str,$dbh); # <segfault> ?> Expected result: ---------------- PHP to return the fetched dba result Actual result: -------------- Segfault Program received signal SIGSEGV, Segmentation fault. 0x000000000171f190 in ??
