Hello, I think that this is not so big problem. But just to be safe, could you check the following definition ? In include/elf/dwarf2.h of gdb-6.6/6.7, #define DW_AT_hi_user 0x3ff0 and in P.138 of dwarf Debugging Information format, version 3, DW_AT_hi_user 0x3fff Thank you, Yoriko Komatsuzaki (yoriko@sm.sony.co.jp)
