Yeah, that's pretty straightforward.

Here's a timeline on cp-demangle.c (times are from the src/ archive).

  2003-05-03  Fix typo in "std::basic_istream ... char_traints ..." [sic] 
  2003-08-12  Fix license (no code change)
  2003-08-19  Some bug fixes to old demangler by ILT
  2003-08-20  Another ILT bug fix to old demangler
  2003-08-21  New demangler

So I'll do:

  gdb HEAD 2003-11-19 16:00:00 UTC
  which is just before the bug fixes of the old demangler,
  
  gdb HEAD 2003-11-21 17:00:00 UTC
  which is just before the new demangler appeared in src
