can you post the config flags? Did you may use --disable-checking ?

This on revision 125313. By coincidence c-common.c was changed just now. 

I am CC'ing people who made recent changes.

Took the liberty of adding Prof Sikora and the release manager, Could not add

Zedenek Dvorak (refusla by Bugzilla@gcc.gnu.org.

This seems to be a case Maintainers no doing the required bootstraps. I am
amazed that nobody else caught for a number of hours.

------- Comment #4 from malitzke at metronets dot com  2007-06-04 21:56 -------
Here is the build machinery used on the powerpc: There were two changes made to
prior runs that caused no boot failures:

BUILD was incresed from 11 to 12

form enable-languages c++, fortran were removed as being pointless to
demonstrate the boot failure. Note that disable-checking is active. 

Onthe other two machines the build machinery is architecture and number of
processor specific other pretty much the same.

In an earlier instance, which lasted two or three month, it was finally
admitted 
that a bas file had for a short time been on the GCC svn repositiry. this file
was not eradicated during further svn updates and so stayed on my system. Given
that I intend (when load on the net is lower) to download a complete fresh copy
of gcc-4.3.0 to see if this kills the problem.

Sorry I overlooked your earlier posting the las too must have crossed each
other.

[Bug middle-end/32209] Boot failure Comparing stages 2 and 3

[pinskia at gcc dot gnu dot org]

------- Comment #5 from pinskia at gcc dot gnu dot org  2007-06-04 22:01 -------
So you found a bug that was only exposed with "  --disable-checking" which
usually means two thing, a gcc_assert really has side effects or something is
being micompiled now.  Also by the way since the trunk works without including
--disable-checking, that means people are bootstrapping as required and just
made a stupid mistake otherwise.

[Bug middle-end/32209] Boot failure Comparing stages 2 and 3

[malitzke at metronets dot com]

------- Comment #6 from malitzke at metronets dot com  2007-06-05 01:29 -------
Fantastic; My stupidity in copying the disable-checking from one of the dozen
top distributors (which make experimental gcc-4.x.y available, patched them
with gcc-3.x.y stuff and referred users to contact gcc maintainers directly.
They stopped it recently not because I asked them to about a year ago as being
counterproductive) revealed something perhaps helpful.

I took the 'disable-checking out gcc-4.3.0 and it bootstrapped fine. However,
grepping warning messages from three days ago and when boot failed I get the
same warning messages (at least exactly the same number). I am glad no being a
maintainer and having to develop a sixth sense about what side-effects or other
are at work.

Peace!

------- Comment #9 from malitzke at metronets dot com  2007-06-05 13:44 -------
Mr. Tobler

Thanks for pursuing this. For me. as a user, it is solved. My analysis, as an
outsider, points to the corruption, inadvertent chang, update malfunction of an
include file shared by the *.c files leading to the *.o files. Looking for the
1...n level include files might give a clue. If you think I could be helpful do
not hesitate to ask.

Cheers.
