Description at@altlinux.org 2005-07-29 01:19:22 MSD 
$ bash -ec 'trap "echo rm lock" EXIT; echo lockfile; false'
lockfile
rm lock
$ bash -ec 'trap "echo rm lock" EXIT; echo lockfile; . ./test.sh'
lockfile
bash: ./test.sh: line 3: syntax error near unexpected token `)'
$

What a funny shit.  I acquire lockfile, install exit handler, source
something and then -- suddenly! -- the exit handler is not executed.
Lockfile is left there forever.

test.sh contains garbage:
case f in
        a) a=1
        b) b=1

Compare this to ash:

$ ash -ec 'trap "echo rm lock" EXIT; echo lockfile; . ./test.sh'
lockfile
./test.sh: 3: Syntax error: ")" unexpected (expecting ";;")
rm lock
