--- Comment #1 from Darren Tucker <dtucker at dtucker.net> ---
Looks like it's an integer overflow caught by -ftrapv:

$ gdb --args ./ssh -o "ConnectTimeout=2147484" localhost
[...]
(gdb) run
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".

Program received signal SIGABRT, Aborted.

1526            timeout_ms = options.connection_timeout * 1000;

timeout_ms is an int.
