In the error message when you use just -fsanitize=thread:

GCC says that -pie or -shared is needed to use -fsanitize=thread, but that is
not enough on amd64:

GCC-4.8's(from experimental) -fsanitize=address flag is not working:

ct the bug is gone, and if I upgrade to libc6
2.13-0exp5, VLC's dec.c seems to be compiled correctly too.
Should gcc-4.6 depend on glibc >= 2.13?
Or should gcc-4.6 provide a fixed prototype for memmove via fix-includes?

According to the GCC plugin documentation plugins should declare a symbol

However the gcc-4.4 in Debian loads the plugin regardless.

gcc-4.5 with -flto doesn't work with -fPIC properly.
Simple testcase:
int entry(int a)
{
return bar(a)+1;
}
int bar(int a)
{
return a+4;
}

GCC-4.5 has a gold linker plugin to do LTO, see
http://gcc.gnu.org/wiki/whopr/driver
It should already be built during a normal gcc-4.5 build,
the plugin should be called liblto-plugin.so.

I have manually reduced the previous testcase (it is 4K now, vs 32K).
The same testcase can be used for both x86_64 and x86(-32).
When I compile with -O3, or -O2 -finline-functions incorrect code is

recompile the entire archive, and see which .o,.so,.a, and
