gprof on OS X Tiger--still broken



I have the same problem as described below, but on Mac OS X 10.4.6.
The bug was reported on May 24, 2005 (or possibly earlier).  Certainly
Apple has had time to fix it.  Will they?  Just the latest frustration
trying to switch from Unix to Mac...

Hi,
Thanks for that info! I've bug reported this problem as "Problem ID:
4123355" last week. Haven't received any further information from apple
however.
