--- Comment #22 from Vincent Lefèvre <vincent-gcc at vinc17 dot net> ---
I get the same kind of errors with "make check" for GMP 6.1.1 by using GCC
6.2.1 and LTO (-flto=jobserve -fuse-linker-plugin), e.g.

/tmp/ccZvS3pG.ltrans0.ltrans.o: In function `main':
<artificial>:(.text.startup+0xc): undefined reference to `tests_start'
<artificial>:(.text.startup+0x17): undefined reference to `mp_trace_base'
<artificial>:(.text.startup+0x43): undefined reference to `__gmpn_random'
[...]

but this is plain C, not C++. Is this the same bug? (I'm wondering because this
bug is attributed to the c++ component.)
