If you are indexing the same data in the same order every time and the target moves with trivial changes of code or flags.. that usually means MEMORY CORRUPTION!!! Unfortunately these types of errors are difficult to duplicate on other machines/platforms. Valgrind is a nice open source memory debugger.. have you used it before? %valgrind htdig xxx yyy This will definetly help find a memory error, but will also drown you in output sice htdig is pretty bad with memory leaks.. but you can dissable leak detection and look only for memory corruption. > When I compile htdig with that flag, the error does not occur. > However, I'm attaching a trace for htdump from a dig performed > without the flag, in case that helps. I hope it isn't too big... Wow, very interesting since the debugg output doesn't do much. FYI: the other way to activate the DEBUG_CMPR flag is to make line 64 of mp_cmpr.c active. This way you can compile htdig normally and reduce the number of variables changing in the experiments. There are 12 spots in mp_cmpr.c where addtional code is executed with the flag. Three of them do nothing but a printf with no variable access.. they can be ignored. It would be interesting to comment out each of them except for one and see what the results are. Let us know what you find. I'd also like a link to your test data if you can put it up on a high bandwidth server.. and a copy of your conf file and commandline htdig options. I'd like to run Insure++ on it. Thanks. Neal Richter Knowledgebase Developer RightNow Technologies, Inc.
