Yes, take a look at the ChangeLog files (gcc/ChangeLog and
gcc/cp/ChangeLog).  Then, you can take a look at cvs diff -D 'before'
-D 'after', or even cvs update -D 'whenever', and try compilers
inbetween.  If you know how to binary search, you can shorten the time
required to find it.  Once you narrow it does to one change in the
ChangeLog, you pretty much have the culprit caught.

If someone would build a compiler each day and archive it, when
someone else reports a new problem you can then binary search on
prebuilt compilers and find when the problems went in fairly quickly.
$150 for 4 GB is a lot of compilers for not much money.
