Hi,

   The following transcription demonstrates gdb 3.0 going into                
an infinite loop:

Hi,

   Could someone please tell me if there is any way to emulate the dbx
``trace'' feature with gdb 3.0?  For example, I'd like to print out
some diagnostics (e.g., parameter list, etc.) every time a particular
function is called, and to have the debugger just keep running
automatically after each output.

   Another useful ability would be to have the debugger *stop*
everytime it entered any and every function.  Is this also possible
using the conditional break feature?

   thanks,
   
      Doug Schmidt
