The following patch silences the failures:

 #include assert.h
 #include unistd.h

However, while I understand that -mtune=* can change the content of dump files
as in pr59494 without any side effect on the generated code, I think the above
patch is only papering over a real bug.

Just -mtune=corei7:

make check-c++ RUNTESTFLAGS=--target_board='unix{-m32\ -mtune=corei7}'
cilk-plus.exp=catch_exc.cc

is sufficient to reproduce.
