This means that the address range of either the psymtab or symtab is
incorrect. It could be either incorrect debug information (probably in
the linker relocation handling) or it could be a GDB bug (probably in
dwarf2read.c). You can't use readelf but I assume you can get one of
the other DWARF debugging tools to work - maybe dwarfdump - and figure
out what the actual bounds of the blocks in question are?
