There is insufficient information here to even guess.

What kind of hardware? Distro? Kernel version? Compiler? Libraries
and versions? Configure flags?

> binary is from the distribution rpm

In that case you need to report this to whoever built that binary. We
don't know what changes have been made to it. If you (or they) can
reproduce the problem built from the stock tarball available from
openssh.com then you can report it here.

RPM with the sources they used is available. If they are same is it
enough? If I reproduce the problem and supply configure options, is it
enough?

Only if you can reproduce it with just the stock openssh without any
third party patches. It's hard enough to debug a system that you can't
interact with without throwing a stack of other changes into the mix.

What were you doing when it crashed? If you can reproduce it, you can
try running sshd in debug mode (/usr/sbin/sshd -ddde) and if you can
capture the log you'll have a better idea of what it's doing when it
crashes.
