+Subject: [PATCH] nm: fix treating an ifunc symbol as a stab if
+ '--ifunc-chars=--' is given
+       
+If an ifunc symbol is processed in print_symbol(), a 'type' field of a
+'syminfo' structure is set to any character specified by a user with an
+'--ifunc-chars' option.  But afterwards the 'type' field is used to
+check whether a symbol is a stab in print_symbol_info_{bsd,sysv}()
+functions in order to print additional stab related data.  If the 'type'
+field equals '-', a symbol is treated as a stab.  If '--ifunc-chars=--'
+is given, all ifunc symbols will be treated as stab symbols and
+uninitialized stab related fields of the 'syminfo' structure will be
+printed which can lead to segmentation fault.
+
+To fix this, check if a symbol is a stab before override the 'type'
+field.  Also, add a test case for this fix.
+
