Compilation fails when building with -DNDEBUG after commit a3189f66a5f2fe86568286fa025fa153be04c6c0.
Here is the error:
dl-close.c: In function ‘_dl_close_worker’:
dl-close.c:140:22: error: unused variable ‘nloaded’ [-Werror=unused-variable]
140 | const unsigned int nloaded = ns->_ns_nloaded;
Add __attribute_maybe_unused__ for‘nloaded’to fix it.
