386: Segmentation fault

[tekknolagi]

I'm not entirely sure what the root of this is (investigating), but 386 seems to produce a segmentation fault when running a binary produced by @akkartik's subx. This is unexpected, because both subx and my machine (Ubuntu Linux, x86) can run this binary. It's a simple program: return 1.

I have attached the traceback and also the hexdump of the binary.

It seems as though ram + p_vaddr points to an invalid location in memory.
