(just making sure...) Yes. I've even rebuild emacs 23.2 with gcc 4.4.2 -g -O2 for good measure, and the crash is just the same. > Is the crash hard to reproduce? Unfortunately yes: it usually takes a couple of hours to occur, and I haven't yet found what triggers it. > Maybe the best bet is to try to isolate the change that caused the crash. > It's very likely that is due to a change in emacs/src/* I fear it's the only way. With the current state of affairs, I cannot give emacs 23.2 to hour users: an editor that crashes regularly is unacceptable. Before going that route, I may try to investigate the core dumps a little bit more, perhaps I find something. Unfortunately, even with the gcc build, gdb cannot make sense of them and doesn't even produce a backtrace. > Could you try to bisect to find the bad change ? Sure, although this will probably take weeks, given the amount of change between 23.1 and 23.2. > (I'd try the git mirror, git bisect is very fast and reliable) I didn't even know that existed: last time I looked the cvs mirror was gone due to unreliablity, so I had to build/learn bzr to checkout the current version. I'll give it a try. Thanks. Rainer -- ----------------------------------------------------------------------------- Rainer Orth, Center for Biotechnology, Bielefeld University
