It may be...

My guess - the var_attr_used_disabled symbol is missing from the dynamic
symbol table, and so the regexps are failing to find any match.  As for
why the symbol is missing, I would guess name mangling or name prefixing.
Maybe your system is prefixing symbols names with some text ?

You could try repeating the test sequence without the -Wl,--dynamic-list,pr22983.t
option on the final link command line, and then see what symbols are
stored in the dynamic symbol table.

PS.  If possible, can you tell your mailer not to wrap lines ?  It makes
reading the test output a lot harder...
