Could you try a newer gdb? And, if it still fails, file a bug report?
gdb isn't fully ready for 64 bit DWARF (e.g., CU offsets are still just
unsigned ints), but it shouldn't crash.

gdb's dwarf reader doesn't use the target for this. It just recognizes
the SGI approach unconditionally. See dwarf2read.c:read_initial_length.
