You are right to keep it, but not for the reason you explained.
I forgot that parse_exp_1 advances the string pointer that it is given.
So if we didn't keep the temporary variable, we would screw b->cond_string
(oops!).

This is OK after having fixed a tiny little detail:

Reformat the comment to avoid the '*' at the beginning of each line
and put the final '*/' at the end of the last line, not on a new line:

      /* We just regenerated the list of breakpoint locations.
         The new location does not have its condition field set to anything
         and therefore, we must always reparse the cond_string, independently
         of the value of the reparse flag.  */

Thank you,
