--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
OK, I've just tests GCC 5.3.1, which works fine for me. Can you please try a
more recent compiler than 4.9?
However, using the latest GCC 7.0 branch, I see:
$ cc -c -flto -fprofile-use=/tmp/prof/ -fprofile-arcs -ftest-coverage -I
src/core -I src/event -I src/event/modules -I src/os/unix -I objs -o
objs/src/core/nginx.o src/core/nginx.c
src/core/nginx.c: In function ‘ngx_get_options’:
src/core/nginx.c:1540:1: internal compiler error: Segmentation fault
}

I'm going to attach tree dump of the problematic function. I'll have a fix for
that.
