            Bug ID: 67158
           Summary: ICE dwarf2out.c:19910/gen_inlined_subroutine_die, at :
                    Compiling gcc6.0 with gcc6.0 -flto
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dilyan.palauzov at aegee dot org
  Target Milestone: ---

I run

/git/gcc/configure --enable-host-shared --enable-threads=posix
--with-arch=haswell --enable-__cxa_atexit --enable-languages=c,c++,lto,jit
--enable-targets=all --enable-nls --with-linker-hash-style=gnu
--with-system-zlib --disable-multilib --prefix=/usr/local/gcc60

/usr/local/gcc60/etc/config.site contains:

export CC=/usr/local/gcc60/bin/gcc
export CXX=/usr/local/gcc60/bin/g++
export   CFLAGS="-pipe -O3 -flto -fno-fat-lto-objects"
export CXXFLAGS="${CFLAGS}"
export LDFLAGS="-Wl,-O1,-z,relro,-s -flto=4"

where/usr/local/gcc60/bin contains a freshly compiled gcc6.0 (but without
passing -flto when building it)

and still at stage1:

++ That sounds like very useful feature.

Possibly also happens with bootstrap-lto and BOOT_CFLAGS=-g, that is, during
stage2/3 when not optimizing (?)

I am also seeing this problem when compiling some packages of Redhat Linux
with gcc trunk dated 20150813.
