Bug #14533 Updated: snmp seg fault

ID: 14533 Updated by: lobbin Reported By: kancha2np@yahoo.com Old Status: Feedback Status: Closed Bug Type: SNMP related Operating System: RH Linux 7.2 PHP Version: 4.1.0 New Comment: No feedback. Closing. Previous Comments: ------------------------------------------------------------------------ [2001-12-15 04:55:09] mfischer@php.net Hmm, seems so. Can you recompile the RH package with debug symbols enabled (or installed a version with debug symbols?) Or grab the latest ucd-snmp from source. Btw, please paste a small, self-contained, reproducea easy copy & paste script too. Feedback. ------------------------------------------------------------------------ [2001-12-15 04:05:17] kancha2np@yahoo.com I'm using RH Linux 7.2 php 4.1.0 with ucd-snmp that comes along with the linux distribution. My configure parameter is as follows ./configure  --with-apxs=/usr/sbin/apxs --enable-calendar --with-pgsql --with-snmp --enable-ucd-snmp-hack --enable-wddx --enable-sysvsem --with-sysvshm --enable-inline-optimization --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl The compilation is smooth, but when i execute any snmp related functions i get segmentation fault. I had got same problem with php 4.0.6 as well and i changed to 4.1.0 but the problem persists. gdb out is as follows: Core was generated by `php snmp.php'. Program terminated with signal 11, Segmentation fault. Reading symbols from /lib/libdl.so.2...done. Loaded symbols for /lib/libdl.so.2 Reading symbols from /lib/libcrypt.so.1...done.

I'm tring with fresh source of ucd-snmp. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14533&edit=1
