Description
Be sure the
__lock_release_recursive(dirp->dd_lock);is being called before theclosedir(dirp);otherwise it will crash as thedirp->dd_lockis going to be deleted inclosedirand on top of that thedirpis freed also inclosedir.This issue has been there in
newlibfor years, however, it wasn't noticed because first of all LOCK API looks to be barely used, and secondly because it also requires the flagHAVE_DD_LOCKto be enabled.Cheers.
