--- Comment #14 from __vic <d.v.a at ngs dot ru> ---
GCC 7-RC1 now reports

lto1: fatal error: bytecode stream in file ‘lib/libssl.a’ generated with LTO
version 5.1 instead of the expected 6.0
compilation terminated.
lto-wrapper: fatal error: g++ returned 1 exit status
compilation terminated.
/opt/binutils/bin/ld: fatal error: lto-wrapper failed
collect2: error: ld returned 1 exit status

in such situation. Very helpful!
