  Reporter: youfan.noey at gmail dot com
  Target Milestone: ---

Created attachment 35757
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35757&action=edit
config.log file

Compiler being used is: clang-600.0.56

Build with command line command:

cd ~/src/build/gcc && rm -rf *
~/src/gcc/configure --prefix=$HOME/sandbox --enable-languages=c++
--enable-checking=release > /dev/null 2>/dev/null
/usr/bin/time make -j11 bootstrap > out.log 2> err.log

It cause segmentation fault when process

Just updated and tried again, get the same result.

Revision: 224410

After changing

diff --git a/gcc/passes.c b/gcc/passes.c
index d3ffe33..1bc8a36 100644

 }

I get similar error as pr66448 

/Users/jieyuandai/src/gcc/gcc/dwarf2out.c:5693:1: error: ‘void

Retry build with gcc-4.9.2 get the same results.
