Hello again,

When reloading a Caudium module I got this error:

Program received signal SIGSEGV, Segmentation fault.

Might not be the compiler since there is a good amount of code in the start() function of an inherit Caudium module. The bug doesn't appear all the time but quite often anyway. I'm running FreeBSD 4.7 on IA32. PS: This time my installation is clean this time:)
