Hi all,
-------------8<---------- Start Bug Report
------------8<----------
1. Problem Description:
As subject says I compiled the mod_perl2 successfully
and without any problems and everything worked
perfectly.
I needed to debug some code so I recompiled mod_perl2
with debug information.
Now I'm getting Bus Error immediately at startup when
Apache process the configuration
(I think documentation calls it "The open_logs Phase"
- ap_run_open_logs...).
I tried to isolate error and I wrote minimal config:
---------------------------------
LoadModule perl_module /tmp/test/mod_perl.so
Listen 80
ServerName localhost
LogFormat "%h %l %u %t \"%r\" %>s %b" common
ErrorLog /tmp/test/error_log
CustomLog /tmp/test/error_log common
PidFile /tmp/test/m.pid
LockFile /tmp/test/m.lock
---------------------------------
running:
/opt/apache-2.2.2/bin/httpd -d /tmp -f
/tmp/test/this_min.conf
with old mod_perl.so (no debug infos) works.
with new mod_perl.so (debug infos) cores.
Debug versions I created with:
adding -Doptimize='-g' to perl Configure command
adding MP_DEBUG=1 to mod_perl2 "perl Makefile.PL"
command
2. Used Components and their Configuration:
*** mod_perl version 2.000002

/opt/perl-5.8.8/lib/site_perl/5.8.8/sun4u-solaris-thread-multi/Apache2/BuildConfig.pm
