> Fixed for quite some time

You shouldn't close a PR without installing the testcase in the testsuite.  Had
you done so, you would have seen that it isn't fixed at all:

eric@atlantis:~/build/gcc/native32-lto> prev-gcc/xgcc -B prev-gcc -o pr45475
pr45475.c -flto
In file included from pr45475.c:15:0,
                 from :0:
pr45475.c: In function 'foo':
pr45475.c:16:15: internal compiler error: in convert_move, at expr.c:330
Please submit a full bug report,
with preprocessed source if appropriate.
