Why nginx coredump on Suse12 ? Give me some advice, please! about f-stack

[whl739]

I don't know why OpenSSL initialization caused core dump, does the original nginx work fine?
Execute ./configure --prefix=/usr/local/nginx_fstack --with-ff_module --with-debug and recompile.
Paste the backtrace again.

I have been already use "--with-debug", and nginx is more than 10M Bytes.
linux-1ryy:/usr/local/nginx_fstack/sbin # ll
-rwxr-xr-x 1 root root 10390160 Jun 17 15:22 nginx
-rwxr-xr-x 1 root root 5929968 Jun 17 11:35 nginx.old

I try to gdb nginx, and check where it happends.

Nginx 1.12 can work well on this machine, but nginx_fstack (nginx 1.11 ) always go wrong.
And it receive SIGSEGV before main() function,
Does the ff-stack have any openssl-version requirements?

Thanks for LogWang's help, it works ok on suse12.

And something should be taken in account, some funcs is replaced before main() executed. such as:
6961: binding file /usr/local/nginx_fstack/sbin/nginx [0] to /lib64/libc.so.6 [0]: normal symbol strtoull' [GLIBC_2.2.5] 6961: binding file /usr/local/nginx_fstack/sbin/nginx [0] to /lib64/libc.so.6 [0]: normal symbol strstr' [GLIBC_2.2.5]

These funcs in glibc are replaced by same name function in nginx bin file,
Is there any good way to correct it?
