farmdve 7f3c567ae5 X86 zero-byte opcode causes Unicorn to crash. 
The opcode 0x00 translates as `add byte ptr ds:[eax],al`, which leads to
a segfault in Unicorn.

Using a debugger, I believe the crash is located in
`qemu/translate-all.c` in function `page_flush_tb_1`, more specifically
this code `pd[i].first_tb = NULL;`

Willi Ballenthin 197602b806 python README.TXT: clarify working directories 
clarify in which directory to build the core project and install the python bindings. when i went to install the python bindings, i was momentarily confused why the root Makefile didn't have an `install3` target.

Nguyen Anh Quynh be36122d0c Merge branch 'fix-soname2' of https://github.com/JonathonReinhart/unicorn 2015-10-25 09:37:40 +08:00
Jonathon Reinhart efb0c87e39 fix install logic after changing LIBRARY 
Now that LIBRARY is the versioned name (e.g. "libunicorn.so.0"), we
don't need this rename step; just create the symlink for libunicorn.so.
If VERSION_EXT isn't set, then the library we installed already has the
correct name, and no symlink is necessary.

We should probably be running 'ldconfig' to handle this, or better yet,
using libtool.
