No matter if CRYPTOPP_NO_UNALIGNED_ACCESS or not, such problems occur:

When CRYPTOPP_NO_UNALIGNED_ACCESS is defined, *cryptest.exe -v* finishes
successfully.
When not defined - crashes.
Also, what exactly should I report? That PIC does not work properly on
MinGW? And how should I prove it - ask to try compiling Crypto++? That's
how my report looks for now:
*My report (not sent yet):*
> Hello, MinGW project!
> A problem with automatic PIC in MinGW occurs when trying to compile
> Crypto++ on MinGW-32.
> Here is how to reproduce it:
> 1) Download latest Crypto++ sources from GitHub repository
> <https://github.com/weidai11/cryptopp>.
> 2) Run following commands in MSYS terminal:
> $ cd /path/to/cryptopp
> $ make
> $ ./cryptest.exe v
> The test crahes with SIGSEGV. AS Jeffrey Walton, one of the library
> maintainers, says, the problem is caused by incorrect PIC work in MinGW.
> When it is automatic, the test crashes, and when it is force enabled (with
> -fPIC flag), another problem <http://sourceforge.net/p/mingw/bugs/2267/>
> occurs.
