Description Vincent Bernat 2006-06-10 14:42:59 UTC 
lbuscd contains a double free bug.

Something coming in from sock: 5
Lost connection from 5
*** glibc detected *** double free or corruption (fasttop): 0x1001c560 ***

I think, that checking Clients[sock].bufsize before freeing Clients[sock].buf at
line 444 may solve the bug.

I've modified lbuscd to fix the double-free problem.  It seems to work fine for
me. We'd like to get more testing, so we've placed the file on the LTSP wiki,
for people to download and try.
