Hi, all
I report it to gcc bugzilla :http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50351
When I use mingw64 gcc build gcc4.6.2 20110909 using "-flto
-fuse-linker-plugin", an internal compiler error came out:

my binutils edition is :

Is this the LTO bug in gcc4.6 or ld bug?
The error seems likePR45475 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45475>, butPR45475 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45475> don't use LTO.
Thanks.

I try to use gcc version 4.7.0 20110911 (experimental) to build gcc trunk, and
it also has the problem, but shows a different error:

Then there's no need to also email this list.
Discussion of the bug should take place in Bugzilla, not here.
