Bug ID: 81966
Summary: runtime.inc:362:10: error: duplicate member ‘_’
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: go

Target Milestone: ---
Hi,
regarding https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81946 I untared the last
gcc 7.2.0 source. I removed the libgo folder and replaced it with the libgo
folder from the svn trunk source.
the exact version of GCC:
gcc-7.1.0
the system type:
NetgearReadyNAS Duo
(http://wiki.dietpc.org/index.php/DIET-PC_on_SPARC_ReadyNAS)
the options given when GCC was configured/built:
nas-02-90-38:/media/gcc-7.2.0-go# ../gcc-7.2.0/configure
CC=/opt/gcc-7.1/bin/gcc CXX=/opt/gcc-7.1/bin/g++ --enable-languages=c,c++,go
--prefix=/opt/gcc-7.2.0 --with-cpu=v7 --disable-libstdcxx-pch
--disable-linux-futex --disable-libsanitizer --enable-__cxa_atexit
--with-system-zlib --enable-nls --enable-clocale=gnu --enable-debug
--disable-doc --disable-libcilkrts --disable-libitm
