[Bug c++/41194] New: __attribute__ ((__gnu_inline__)) yields x86_64-unknown-linux-gnu when compiled with -O0, but not with -O1

Error messages:

/tmp/ccgtrVyI.o: In function `Color':
/home/chromium/chromium/src/third_party/WebKit/WebCore/platform/ColorData.gperf:254:

/home/chromium/chromium/src/third_party/WebKit/WebCore/platform/ColorData.gperf:254:

Command line:

g++  -O0 -g  Color-stripped.ii

Compiler build configuration:
  ../configure --prefix=/usr --enable-shared \
      --enable-languages=c,c++,fortran,objc,obj-c++ \
      --enable-threads=posix --mandir=/usr/share/man \
      --infodir=/usr/share/info \
      --enable-__cxa_atexit  --disable-multilib --libdir=/usr/lib \
      --libexecdir=/usr/lib --enable-clocale=gnu \
      --disable-libstdcxx-pch \
      --with-tune=generic

The symbols resolve correctly if compiled with "-O1" or if "__attribute__
((__gnu_inline__))" is removed from function definition.
