OK, so here I do get a fail. binutils/objdump: out of memory allocating 365072220160 bytes after a total of 53248 bytes. The file has a symbol table claiming to be 0xff00000000 byte in size, or 0xaa0000000 symbols, requiring that rather huge amount of memory. Since this is driven by user input rather than due to some bug in binutils, it is quite reasonable to report an out of memory error and exit.
