$ ../gcc/configure --enable-version-specific-runtime-libs --disable-bootstrap
--disable-werror --disable-multilib --enable-languages=c,c++

is enough to reproduce the issue.

I can even reproduce without --enable-version-specific-runtime-libs.

Hi,
   I just submitted a patch to the gcc-patches mailing list. Can you try
that out?

Thanks,

Balaji V. Iyer.

Our mails just crossed and I think your patch is fine.
Will try it out tomorrow.

Fixed. Thanks.

BTW fib_serial() in testsuite/c-c++-common/cilk-plus/CK/fib.c is obviously
wrong:

I've measured the serial vs. the cilk+ performance and it looks quite sad:
