Dear Maude Abusers, A new alpha release can be accessed at SRI-CSL in: ~eker/public_html/Maude/Alpha96b/ or downloaded from: http://www.csl.sri.com/~eker/Maude/Alpha96b/ Alpha release site authentication: User Name: maudeabuser Password: bughunter Bug fixes -------- (1) A bug in variant narrowing where trying to generate variants of a ground term resulted in a crash. Reported both by Santiago and Kyungmin Bae. (2) A bug which caused memory corruption with sockets; this was reported by Grigore Rosu on 64-bit machines, but it occurs with less visibility on all machines. (3) A long standing bug in sockets where sockets appear to be dropped on Macs. This was actually reported by Musab AlTurki back on May 11, 2009 and actually results from the interaction of two separate bugs and the MacOS implementation of POLLHUP under certain race conditions. I originally thought this might be the same bug as (2), hence the renewed effort to find it. It was originally reported for 32-bit Macs but would affect any *NIX operating system that reports both POLLIN and POLLHUP when a process is checking for readable data on a socket with poll() and the other end of the socket has be closed. Linux only reports POLLIN which avoids triggering the bugs and the potential race condition. Steven
