[Bug bootstrap/24873] New: gcc 4.0.2 bootstrap report compare fail

[gaojianbin at 263 dot net]

i bootstrap gcc 4.0.2 on AIX 5.2,i got the error message as follows:
-----
Bootstrap comparison failure!
./fold-const.o differs
make[1]: *** [slowcompare] Error 1
make[1]: Leaving directory `/swtdata/emv_emu/emu1/jbgao/objdir/gcc'
make: *** [bootstrap] Error 2
------

i used gnu make already.

is this a bug or anything else?

What compiler are you starting with?
Also what options did you use to do a configure with.
Also could you make sure that you have read:
http://gcc.gnu.org/install/specific.html#x-ibm-aix

1:
I use xls,ibm visual age 6.0 c compiler.

2:configure options is as follows:
../gcc-4.0.2/configure --prefix=/swtdata/emv_emu/emu1/jbgao/gccbin 
--enable-threads=aix  --enable-languages=c,c++ 

3:i have read the install specific about compile on aix ,have no ideas.

i searched the bug database for the related bug, the solving methold have no
use.

------- Comment #4 from dje at gcc dot gnu dot org  2005-11-24 03:56 -------
Many people are reporting that they cannot bootstrap GCC with IBM's VisualAge
compiler.  This appears to be a problem with VAC/XLC, not with GCC.  This bug
should be reported to IBM as a XLC bug.  In the meantime, you need to bootstrap
with an older version of GCC.

no feedback.  apparently the problem was XLC bootstrap.
