The lines are a bit off, but basically we end up hitting the internal error
at mips-tdep.c:mips_pseudo_register_read. I don't think the MIPS backend is
currently crafted to handle reading unknown register blocks.
Then it is a mips-tdep.c bug similar to this i386-tdep.c bug:

In general GDB should not crash when you let it read an arbitrary file.
If you want I can file it as a new MIPS-specific PR and KFAIL it.
