Eric, no not at this time.  Thanks.

Any plans to resubmit the GUPC branch again?

Recently, I've been reviewing changes that we made on the GUPC branch (see
comment #2) that are candidates for the trunk revision (or in this case,
possibly the 4.7 branch).

   if (flag_var_tracking

generating_for_darwin_version = 9
(flag_gtoggle ? (debug_info_level == DINFO_LEVEL_NONE)
   : (debug_info_level = DINFO_LEVEL_NORMAL))

Reading the problem description, unless the option scanning logic has changed
for Darwin, it looks as if this change might still be necessary to suppress var
tracking at -O0?

Log:

* config/darwin.c: Disable var_tracking option
  on -O0 as it is supposed to run only when optimization
  is applied. See GCC bug 49743. 'upcfish' test was
  taking to long to compile.

var-tracking isn't supposed to run at -O0.
