This does sound encouraging as I do often have multiple clients attached to a session. However, I was running a few-day-old CVS HEAD and still had the problem. I just updated to the latest version, but now the server process dumps core when I start tmux. The problem appears to be this change in compat/imsg.c: Index: compat/imsg.c =================================================================== RCS file: /cvsroot/tmux/tmux/compat/imsg.c,v retrieving revision 1.5 retrieving revision 1.6 diff -r1.5 -r1.6 1c1 < /* $Id: imsg.c,v 1.5 2010/06/06 00:08:28 tcunha Exp $ */ --- > /* $Id: imsg.c,v 1.6 2010/11/11 20:41:08 nicm Exp $ */ 114c114 < if ((imsg->data = malloc(datalen)) == NULL) --- > if (datalen != 0 && (imsg->data = malloc(datalen + 1)) == NULL)? The logic here seems broken (if datalen is 0 then it won't return with an error). However, even fixing this: Index: compat/imsg.c =================================================================== RCS file: /cvsroot/tmux/tmux/compat/imsg.c,v retrieving revision 1.6 diff -r1.6 imsg.c 114c114,116 < if (datalen != 0 && (imsg->data = malloc(datalen + 1)) == NULL) --- > if (datalen == 0) > return (-1); > if ((imsg->data = malloc(datalen + 1)) == NULL) tmux now returns -1 all the way up the stack and exits. datalen is 1024 consistently for a while, then it gets big, then it's 0.
