#27543 [Opn->Bgs]: php as cgi with extenstion=overload.so in php.ini crashes

ID: 27543 Updated by: sniper@php.net Reported By: arekm at pld-linux dot org -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: Linux 2.4/2.6 glibc 2.3.3 PHP Version: 4.3.5RC3 New Comment: Thank you for all the irrelevant information..(you obviously ignored the instructions about how to report) Necessary information would only have been: 1. your configure line 2. gdb backtrace 3. Steps how to reproduce Furthermore: Your configure line seems a bit weird since you certainly CAN NOT get a CGI binary with it. You didn't use clean sources when you configured the binary. Get the latest stable snapshot and drop ALL those LDFLAGS / CFLAGS etc., don't try outsmarting the configure.. Also, you should look into the './configure --help' output sometime, some of those options you used don't even exist. And making PCRE extension shared is not very good idea either.. Bogus. (open a better report with the above mentioned information if you still can reproduce the crash with clean sources from latest STABLE snapshot using proper configure line..)

Almost every of my extensions is as loadable module but at this time I'm loading overload.so only.
