I believe this is the bug:

set -o posix
readonly a=0
a=1 command : 2>/dev/null # or use true in place of command :
readonly b=0
echo after

bash-4.1 exited without getting to the `echo after', which is clearly
wrong.  The original version came from FreeBSD's sh regression test suite.
I thought the change in bash-4.2 fixed the problem, but I now think
another change masked the problem without fixing it.  (Try it, it's still
broken in bash-4.2.)

I've fixed the problem and the fix will be in the next release.
