Hi Alan,

Don't know if this would help you track it down... I 
recompiled --without-threads, it seems to have solved the *original* 
problem.

Are threads deemed to be stable yet in 1.1.1?  If so, can it be rechecked? 
What I'm picking up:

MySQL 5.0.21, Muli Threaded
Perl 5.8.8, Multi Threaded
FR 1.1.1, Debug

I don't know the order in which these modules load, so you'll sort that out 
better than me... But...
FR with Theads, cores loading rlm_sql_mysql
FR without Theads, loads rlm_sql_mysql, BUT, now cores loading rlm_perl

I kind of find it strange that it's only with threaded applications that 
this is happening... I know that FreeBSD *had* issues in the past with 
threads, but that is long since gone  MySQL Multi-Threaded is quite normal 
on FreeBSD, and Threaded Perl is also pretty stable these days (according to 
the mailing lists).  Could it be that FR maybe has issues with it?

Right now, without rlm_perl and FreeRadius in a single-threaded compile, I 
have no issues... When I change FR to multi-threaded rlm_sql_mysql crash, 
when FR is single threaded, rlm_perl (because I have a threaded perl 
compile) cores...

The trace for the rlm_perl crash:
read_config_files:  reading dictionary
read_config_files:  reading naslist
read_config_files:  reading clients
read_config_files:  reading realms
radiusd:  entering modules setup
Module: Library search path is /usr/local/lib

Program received signal SIGSEGV, Segmentation fault.
