             Bug #: 54638
           Summary: [4.8 Regression] bootstraping 4.7.2 with 4.8 broken:
                    cc1: malloc(): memory corruption
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: markus@trippelsdorf.de


With:
~/gcc/configure --disable-werror --disable-multilib --enable-checking=release
--enable-languages=c,c++

and:
make BOOT_CFLAGS="-march=native -O2 -pipe" STAGE1_CFLAGS="-march=native -O2
-pipe" CFLAGS_FOR_TARGET="-march=native -O2 -pipe"
CXXFLAGS_FOR_TARGET="-march=native -O2 -pipe" bootstrap

I get:

Please specify -v output of that command (what does -march=native expand to?)
and attach preprocessed source.  Is that stage1 xgcc?

It also happens without -march=native. And yes, it's stage1 xgcc:

That means GCC 4.8 miscompiles stage1 GCC 4.7 with flags -march=native -O2
(just to be sure - also without -march=native for STAGE1_CFLAGS?)

Yes the following also leads to corruption:
make -j4 BOOT_CFLAGS="-O2 -pipe" STAGE1_CFLAGS="-O2 -pipe"
CFLAGS_FOR_TARGET="-O2 -pipe" CXXFLAGS_FOR_TARGET="-O2 -pipe" bootstrap

--- Comment #8 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2012-09-20 17:52:11 UTC ---
4.6.3 also fails to build with the same error. 
I guess 4.8 would also fail if it still could be build without C++.

 %  ~/gcc/configure --disable-werror --disable-multilib
--enable-checking=release --enable-languages=c --disable-bootstrap
 % make

is sufficient to reproduce.

A simple input causes:

[hjl@gnu-mic-2 gcc]$ cat /tmp/x.i
typedef int TItype __attribute__ ((mode (TI)));
int
foo (TItype a, TItype b)
{
  return a < b;
}

My guess is r186590

        * ira-int.h (ira_allocno_object_iter_cond): Avoid out-of-bound
