From: alexiadeath at hotmail dot com Operating system: Slackware Linux 10.1 PHP version: 5.0.4 PHP Bug Type: Reproducible crash Bug description: Apache child segfaults(11) in strlen
Description: ------------ in php 5.0.4 with either apache 2 or apache 1.3 (there is no difference) click on phpMyadmin Browse tab generates a partial page with segfault(11) in apache log. Failed to find the exact cause because the moment of segfaulting DEPENDS on minor changes in the code for example an added echo. With php 4.4 nothing like this happens and page loads properly. on windows with apache2 and php 5.0.5dev the problem simply does not exist. Cant try the latest dev because of the disc space limitations of my box. no room for compile tools. all items involeved are a maching set of precompiled packages from linuxpackages site. Reproduce code: --------------- In phpMyadmin every time on clicking browse. go try. Expected result: ---------------- phpMyadmin page with database results. Actual result: -------------- page with just tab headers.
