            Bug ID: 61785
           Summary: Sigsegv with enabled optimize -Os , -O2 in
                    sample_format_size
           Product: gcc
           Version: 4.8.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

Created attachment 33109
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33109&action=edit
i486-openwrt-linux-g++ -v output

I get a SIGSEGV when running the binary compiled with default switches
(containing -Os) in qemu.
If I compile with -O0 the program is working.

GCC 4.6.4 is generating working code with -Os
4.8.0, 4.8.3, 4.9.0 do not work with -Os ; -O0 binaries work



Source is from mpd 0.18.11
gcc is used in OpenWrt buildroot to compile it for target arch (x86)
I opened a ticket on mpd bugtracker, provided gdb output and was told it's a
compiler bug - thats why I opened a ticket here.

the mpd bugtracker ticket is: http://bugs.musicpd.org/view.php?id=4024
