The other one was tracked down by John Millikin to a resource allocation bug in haskell-gnutls and fixed. - -I have written a test case that reproduces the problem -- just forking a dozen threads that each try to connect to the google xmpp server and then close the connection. After a dozen or so succeed, one will reliably cause a segfault. Forwarded this test case to John. -"""]] |
