Bootstrap Heisen-ICE?


  Since Friday (Indian Standard Time, GMT+5:30), I've
been seeing a bootstrap failure (ICE) while compiling
insn-attrab.c (on i686-pc-linux-gnu with --disable-checking)
the first time around, but the moment I try to reproduce it,
the build goes through fine! It'll then randomly ICE in
either libstc++-v3 or libgcj - again, running make again
will get past that failure.

If it matters, till Monday, the machine was using Red Hat
Enterprise Linux 3 Update 2, but even moving to Update 3
hasn't helped matters one bit.

Has anyone else been seeing this? I want to help track
this down, but as I said earlier, the moment I try to, it
disappears. :-(

The machine has hyperthreading enabled and I'm using an
SMP kernel (2.4.21-20.ELsmp from Red Hat). I configure

$GCC_SRC_DIR/configure --prefix=$HOME/gcc --enable-languages=c,c++,java \
--disable-nls --disable-checking --disable-libmudflap \
--disable-debug --enable-threads=posix --enable-__cxa_atexit

and I use a simple "make bootstrap" (note: not a parallel

regularly till around a month ago and no hardware has been
