There is insufficient information here to even guess.
What kind of hardware? Distro? Kernel version? Compiler? Libraries
and versions? Configure flags?

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. -- You are receiving this mail because: You are watching someone on the CC list of the bug.

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. -- You are receiving this mail because: You are watching someone on the CC list of the bug.
