I freshened my svn tree to rev 206077 and get an ICE while compiling libcilkrt.
Configure options:
env CFLAGS=-O2 ../src/configure \
--enable-languages=c,c++ --disable-bootstrap --disable-checking

I think the issue is that libclkrt is being compiled with the first stage
compiler.
--disable-bootstrap --enable-checking : has no problem
--enable-bootstrap --disable-checking : has no problem
Also, it is worth noting that with "-O2" it fails with SEGV, but with "-O0" it
runs out of memory (virtual memory exhausted: Cannot allocate memory), which I
have 4Gb.
