You can only have more than one debug_info section when -feliminate-dwarf2-dups is used. This isn't a commonly used option, and there may be a number of problems with it. This is allowed by DWARF3, but not by DWARF2. I see how your patch might help now. The debug info is 32-bits as I mentioned earlier. The problem here is that pointers are 64-bits. read_address uses addr_size, and hence is reading a 64-bit address when it should be reading a 32-bit address, thus getting a number that is too large. Your fix adding 64-bit debug support helps because in the 32-bit case you replaced the read_address call with a read_4_bytes call, which correctly reads the 32-bit value we want. However, this is speculation, as I don't know how to reproduce the failure. I don't understand why this hasn't come up before. Also, it isn't clear what this has to do with the further information you have provided about multiple debug_info sections. -- Jim Wilson, GNU Tools Support, http://www.specifix.com _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
