(In reply to H.J. Lu from comment #3)
It was caused by r217655.
The problem was introduced earlier when function_code field in
tree_function_decl was extended to 12 bits. LTO streamers were not fixed
appropriately. r217655 increased BUILT_IN_COMPLEX_MUL_MIN value and put it out
of 11 bits which revealed the problem.
With this patch compiles OK:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64075 --- Comment #6 from Dmitry Gorbachev d.g.gorbachev at gmail dot com --- The patch works, thanks! But the committed test is incorrect, because the original, unpatched compiler, does not fail on it. It failed on functions __mulsc3, __muldc3, __mulxc3, __multc3, __divsc3, __divdc3, __divxc3, and __divtc3.

It failed on functions __mulsc3, __muldc3, __mulxc3, __multc3, __divsc3, __divdc3, __divxc3, and __divtc3. Committed test is what you attached as a reproducer with function renamed to 'test'. Why shouldn't it work? I used it to reproduce and debug the issue on today's trunk compiler.
