[comp.sys.next] problems with message tracing and HashTables

combs@sumex-aim.stanford.edu (Dave Combs) (07/14/89)

Gang,
Has anyone had problems in using the "msgFlag" variable to enable message
tracing in 0.9?  Whenever I set the flag to YES, I will get one or two
trace messages, then invariably the application bombs with a protection
violation in function _prnFrame.  Has anyone seen this before?  I couldn't
find anything in the release notes or online documentation (or Stepstone
manuals, for that matter).

Second, has anyone been using the HashTable class successfully?  I've tried
debugging what is going into the insertKey:value: method, but it doesn't
seem to agree with what I'm trying to pass in.  Sometimes the system
seems to work, and other times it bombs, with a protection violation in 
malloc_debug in [HashTable _insertKeyNoRehash:value:].

I'm tearing out what's left of my hair on these two.  I can't debug the
HashTable problem much at all without the message trace, because just trying
to break the method in gdb won't allow me to print out the method arguments.

Any help would be GREATLY appreciated.
  (Pledges about kissing of feet and undying gratitude heard in 
   the background...)
