It seems to me that Bash is behaving as expected. When the terminal
resizes, a SIGWINCH signal (Window resize signal) is sent to the
foreground process. You seem to have defined a trap for this signal,
and the action of that trap is to kill the current shell with SIGINT
(2).

If you wish for the current shell to continue running after a terminal
resize, then set the signal disposition for SIGWINCH to ignore.
