For one your resolve.c patch is incorrect, see PR 30549.

------- Comment #13 from martin at mpa-garching dot mpg dot de  2007-01-23 16:53 -------
Could this be an enable-checking issue?

I'm only seeing the problem when configuring with "--enable-checking=release",
otherwise the compiler bootstraps fine.
This is on i686-pc-linux-gnu.

(I also have
export BOOT_CFLAGS="-O2"
export CFLAGS="-O2"
if that makes a difference.)

Part of cp/parser.c with --enable-checking=assert

This is the part of cp/parser.c configured with --enable-checking=assert.
Because different -enable-checking settings effectively create slightly
different gcc source codes seen by gcc, gcc may or may not be determine
bases will be initialized or not.

Sorry, the previous message has been truncated:

Has there been any progress with this bug?
I can confirm it and I need the mentioned patch to be able to compile
 the current trunk:
-  tree bases;
+  tree bases = NULL_TREE;

I understand that some configurations work and some fail. Also I
 cannot confirm the depency of bug 30549 since 30549 was fixed
and this one still occurs...
