Using Eric Botcazou's test case, it also has the problem.
gcc lex.c

has no problem

gcc -flto -fuse-linker-plugin lex.c

it shows
In file included from lex.c:15:0,
                 from :0:
lex.c: In function 'foo':
lex.c:16:15: internal compiler error: in convert_move, at expr.c:330
Please submit a full bug report,
with preprocessed source if appropriate.
