Options given to Makefile.PL when compiling mod_perl:
perl Makefile.PL APACHE_SRC=../apache_1.3.33/src DO_HTTPD=1 USE_APACI=1 
PREP_HTTPD=1 EVERYTHING=1

(and subsequently, in anticipation of running gdb:)
perl Makefile.PL APACHE_SRC=../apache_1.3.33/src DO_HTTPD=1 USE_APACI=1 
PREP_HTTPD=1 EVERYTHING=1 PERL_DEBUG=1

In each case of compiling mod_perl, all tests were successful.
As I said, any suggestions on how I might fix this, such that I can use 
Apache::AuthDBI to authenticate on the Fedora Core 1 server, would be 
appreciated. Thanks.

In moving some web sites from a server running Red Hat Linux release

Apache::AuthDBI, which were working normally on the RH 7.3 server, 
are producing segfaults on the FC1 server.

I'd suggest to cleanup your perl's lib tree first, nuking all paths 
with 5.8.2, 5.8.1 and 5.8.0 in it. May be you get some binary 
incompatible module loaded which causes the crush.
That appears to have solved my problem. I needed to install DBI and 
DBD::mysql from source after removing the 5.8.0, 5.8.1, and 5.8.2 paths 
from the perl lib tree, because the FC1 distribution apparently came 
with those installed under 5.8.0. But having done that, Apache::AuthDBI 
is authenticating properly, with no segfaults.

Thank you very much for your help.
Your perl is thread-enabled, do you by chance spawn perl threads 
anywhere? Did you try building perl with -Uusethreads?
As far as I'm aware, we're not using threads anywhere on the server. I 
haven't tried building perl with -Uusethreads, no.

Thanks again.
