Start gdb with any program you want to debug 2. set a pending breakpoint, e.g. "b nofile.cxx:54" 3. type "condition 1" + Tab This seems to come down to gdb/breakpoint.c:condition_completer which has the code: ALL_BREAKPOINTS (b) { 1016 int single = b->loc->next == NULL; struct bp_location *loc; int count = 1; for (loc = b->loc; loc; loc = loc->next) { That 'int single' line is where it segs because b->loc is NULL; I think turning it into something like int single; ... single = (b->loc)?(b->loc->next==NEXT):1 would do it, but I've not really dug into the datastructure to check what else that might do. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 7+ messages in thread
