That could indicate that it is looping in redisplay.

If you continue stepping, do you ever get out of redisplay?  That is,
does redisplay_internal return?  You can find this out by repeatedly
typing "finish", until it does not return to a higher frame.

If it never gets back to wait_reading_process_output (frame #10 in
your backtrace), that would explain why Emacs is not responding to
your input.  The next step then would be to understand why it gets
stuck in redisplay.
