It looks like bash is actually broken in POSIXLY_CORRECT mode, then:
$ echo $BASH_VERSION
3.1.17(1)-release
$ POSIXLY_CORRECT=1
$ foo=bar}
$ echo "${foo%'}'}"
bar
My interpretation of the correct behavior is that it should remove a
single quote from the end of foo, and then print '} literally (that is,
single quote and brace).
Well strictly speaking this is allowed by the standard as this usage
contains an odd number of single quotes inside an ${...} expression
enclosed by double quotes, which behaves in an implementation-specific
manner.
Cheers,
