we ran into a similar condition using 5.0.27 in a PHP application.. in
our case it had nothing to do with the version. check your server
logs for evidence of a restart. What we had done was naively imported
innodb extents from a v.4 datbase which seemed to work fine at first
but in fact setup an edge condition whereby certain perfectly valid
SQL was triggering a GPF on the server. I realize that's quite
unlikely that you have performed a similar sloppy import but there is
likely some edge condition on your server (wierd permissions in the
data directory, corruoted tables, etc.) but I still recommend that you
scrutinize your server logs for evidence of a spontaneous restart. If
that turns up nothing, you might try a fresh install of mysql on a
separate host to see if the problem persists. Worst case, there is an
upgrade patch available which might magically raise you above the
