And the name attribute is missing in dwarf2. So the semantic error is thrown in elaborate phrase. So maybe construct a pure function to access index member. -- What |Removed |Added ---------------------------------------------------------------------------- Summary|nfs.stp nfs.aop.readpage |nfs.stp nfs.aop.readpage |uses field "index" which |uses field "index" which |isn't available in linux |isn't available in linux |2.6.22-rc1 |2.6.22-rc1 http://sourceware.org/bugzilla/show_bug.cgi?id=4519 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ^ permalink raw reply [flat|nested] 4+ messages in thread
