Yes. > Have you tried using valgrind, or getting a gdb backtrace, or reducing > it to a simpler test case? No, yes, no. I've stared at backtraces on Mac until I'm blue in the face, and couldn't figure out what was going on. I finally have some insight, though, from dmalloc (and playing with TotalView a little): using a memory debugger set to repaint freed memory, I can force a segfault earlier (but still in the same destructor sequence from my code's perspective) where it seems that a slot is being destroyed twice. I'll work on assembling a simpler test case this afternoon. - Michael _______________________________________________ libsigc-list mailing list libsigc-list@gnome.org http://mail.gnome.org/mailman/listinfo/libsigc-list
