64 bit libflashplayer is hard coded to use /usr/lib/ and on Fedora 11
the 64 bit alsa-libs live in /usr/lib64/. I'm not sure that is a problem
with a 64 bit system, libflashplayer or just Fedora's packaging policy.

I am guessing that it affects a lot of people.

The stability issues I have seen are not related to libflashplayer. That
issue is more of a usability issue in that firefox/libflashplayer
doesn't release the alsa device which makes it hard to use jack or other
apps that require access to the alsa device.
