This is likely a problem rather specific to my configuration, but I ran into a problem when trying to send messages (sendmessage.php) during offline development using XAMPP and mysql (OS X Lion).  It failed with the following error in the apache log:

mysql error: [1436: Thread stack overrun:  5848 bytes used of a 131072 byte stack, and 128000 bytes needed.

Turns out that the XAMPP setup for the thread_stack is too low and needs to be beefed up>

/Applications/XAMPP/etc/my.cnf (may differ depending on OS):
...

thread_stack = 64K  # NEEDS TO BE HIGHER, 192K for 32bit OS for example

...

Making this change and restarting mysql/apache solved the problem.  Just thought I should report it in case others run into this problem.
