 well, the bug-or-feature was introduced between

 Sep 16 08:16:13 UTC 2002, and Sep 20 10:00 UTC 2002

 however, trying to bootstrap, a usual 2 stage bootstrap, using gcc 3.2.2 
 20021204 (prerelease) as bootstrapping compiler, the Sep 20 10:00 UTC 
 2002 gcc cvs trunk, then 3.3 experimental, gets me this ICE:

 however, if I just build the compiler, i.e., not doing a bootstrap, I do 
 not get the ICE.

 Furthermore, trying to run gdb gets me nowhere, I suppose from the fact 
 that it's a 64/bit binary

 I'm just plain out of ideas right now...

 So, I wonder what the analysis is?
