    In gdb 4.6 on a sparcstation, I had a problem with the "break" command.
   Specifically, it refused to take an assembly language address for an
  argument.  Following is a transcript of part of the gdb session; the
  first instance of the rror is marked with "<===".

(gdb) help break
Set breakpoint at specified line or function.
Argument may be line number, function name, or "*" and an address.
If line number is specified, break at start of code for that line.
If function is specified, break at start of code for that function.
If an address is specified, break at that exact address.
With no arg, uses current execution address of selected stack frame.
This is useful for breaking on return to a stack frame.

Multiple breakpoints at one place are permitted, and useful if conditional.

Do "help breakpoints" for info on other commands dealing with breakpoints.
