Re: Bug #4045: Apache segfaults when PHP is loaded

I'm using the same .src.rpm from the MySQL site and have no problems. This is on RedHat 6.0 box running a 2.2.14 kernel. At 03:56 AM 4/5/2000, you wrote:

Apologies for the lousy webmail (iName) but my usual server is sitting beside me (instead of sitting at the ISP) and is the one with the offending problem on it. ---- you wrote: MySQL from rpms? If so, try compiling from source and see if you have the same problem. Well, both. I did rpm --rebuild MySQL-3.22.32-1.src.rpm and then installed the subsequent binary RPMs. It seems to me that I remember chasing down IO_new_*() related problems before and it ended up being a glibc mismatch problem of some sort. Is it possible that there's something f?cked in the source RPM that doesn't occur with the tarball? Or could it be some sort of weird compiler-related thing? (optimizing/linking?) How about upgrading glibc etc.? It should be of note that PHP4RC1 didn't barf but it did compile with warnings. Although *that* httpd, modperl, Scoop (scoop.kuro5hin.org), and Storable.so didn't get along well either (*sigh*). I'm up for helping to chase this down, if anyone can give me the "... for Non-Coder Types" instructions or experimental patches to try. On 5 Apr 2000 admin@weirdness.com wrote:

Apache starts and runs okay without PHP loaded. This has been an

ongoing thing since ~3.0.13 on Mandrake 7.0 (i.e. I can reproduce it on different machines using Mandrake 7.0) ------------------------------------------------------ Get free personalized email at http://four11.iname.com -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: php-dev-unsubscribe@lists.php.net For additional commands, e-mail: php-dev-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
