receiving memory corruption when trying to run monit

[Adam Greene]

Hello,
I installed monit from source on CentOS.

-bash-3.00# uname -a
Linux <node name> 2.6.9-42.0.2.EL.xs148xenU #1 SMP Sun Oct 15  
08:31:21 EDT 2006 i686 athlon i386 GNU/Linux


If the config file doesn't contain any monitoring checks, it boots up  
just fine.  However, if I quit it, I see this:

-bash-3.00# pwd
/etc/monit.d
-bash-3.00# ls
includes  monitrc
-bash-3.00# monit
Starting monit daemon with http interface at [*:8135]
-bash-3.00# monit quit
monit daemon with pid [30556] killed
*** glibc detected *** double free or corruption (!prev): 0x090e7448 ***
Aborted

now if I put a basic cron check in the config file, it won't even  
startup...it will fail with this:

-bash-3.00# pwd
/etc/monit.d
-bash-3.00# ls
includes  monitrc
-bash-3.00# monit
Segmentation fault

I've tried recompiling with:
export MALLOC_CHECK_=0

but no luck.  I'm totally stumped!  Does anyone have any ideas on how  
to proceed?

thanks!
Adam


ps.  The config file in question:

set daemon     120
set logfile syslog facility log_daemon
set mailserver 127.0.0.1
set alert      address@hidden
set mail-format { from: address@hidden }
set httpd port 8135
