testcase

Due to some stray CFLAGS I found myself compiling libstdc++ with -flto turned on, which yielded:

$ arm-oe-linux-gnueabi-g++ -O2 -flto -g -fpermissive -std=gnu++0x atomic.ii -S

Same result on PowerPC with gcc 4.6.1:
/usr/lib/gcc/powerpc-lynx-lynxos/4.6.1/../../../../powerpc-lynx-lynxos/include/boost/lexical_cast.hpp: In instantiation of 'bool boost::detail::lexical_stream_limited_src<CharT, Base, Traits>::operator<<(long double) [with CharT = char, Base = std::basic_streambuf<char>, Traits = std::char_traits<char>]':

/usr/lib/gcc/powerpc-lynx-lynxos/4.6.1/../../../../powerpc-lynx-lynxos/include/boost/lexical_cast.hpp:971:21: internal compiler error: in write_builtin_type, at cp/mangle.c:2167

This only appears with -O2 -flto and passes -Os -flto.

gcc -v:

I would say put a breakpoint on write_builtin_type and see what a heck is that type!
Comment 3 Paolo Carlini 2013-05-25 08:59:58 UTC 
I'm pretty sure it's a Dup, otherwise, if the issue persists, please re-open, thanks.
