Phew! So, I'm back to debugging the The exactly same thing happened to my machine. It took me several weeks before I lowered memory clock. My machine has been running fine for over a year under very heavy load. BTW, this is what I use to test ia32 on Intel64: PATH=/usr/local32/bin:/bin:/usr/bin .../configure --prefix=/usr/6.0.0 --enable-clocale=gnu --with-system-zlib --enable-shared --with-demangler-in-ld --enable-libmpx i686-linux --with-fpmath=sse --enable-languages=c,c++,fortran,java,lto,objc where /usr/local32/bin has ia32 binutils. -- H.J.
