Icecast dev - Nov 2006 - win: crash with exception c0000005 on source exit

Hi,

we have a reproducable crash with icecast 2.3.1 on a windows machine 
(Win 2003 server):
On exit of the last source (an ezstream acting as a fallback source) the 
server crashes with non-handled exception c0000005. The famous last 
words in the log:

Is this a known issue, or does anyone have some idea about the cause? 
Any help appreciated!
