            Bug ID: 3101
           Summary: sshd core is seen when FIPS mode is set
           Product: Portable OpenSSH
           Version: 7.9p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: critical
          Priority: P5
         Component: sshd
          Assignee: unassigned-bugs at mindrot.org
          Reporter: navneet.kumar.garg at gmail.com

sshd core is seen when FIPS mode is set and we close the ssh connection
using 'exit' command. Issue is seen only in FIPS mode. Pasted the stack
trace below. sshd binary is non-debug, so limited information is shown
in the stack. How do I get debug sshd binary so that we can have more
debug information in stack trace? Issue is seen from certain ssh
clients, like issue is seen consistently using MobaXterm version 10.9
build 3656. Appreciate any input on this.

# sshd -v
unknown option -- v
