The processor is 32 bit, but the software amd64 and everything works. Why?

There is a 32 bit processor, according to the description support 64-bit instructions - no.
On my computer "uname-a" :
Hostname Linux 4.5.0-0.bpo.1-amd64 #1 SMP Debian 4.5.1-1~bpo8+1 (2016-04-20) x86_64 GNU/Linux
+ installed the 64 bit software from the repositories.

And it works!

Until the segfault does not occur with and something or other, the application crash.
It's like something related to the processor architecture and number of bits of software?

On 32-bit percent 64-bit kernel just not booted up. Or the model is different, or Intel a typo.

So your link is obviously not about your percent - toby.Barrows commented on July 12th 19 at 17:04

this is the 64-bit processor - anne_Stiedema commented on July 12th 19 at 17:07

You and x64 OS, so that the percent you just x64.
Segfault not associated with this. Here we must deal with the software and the dependencies.

Apparently you are confused by the presence of the amd64 in the name of the operating system. In the names of Debian and Ubuntu (not sure how) write the amd64 for a 64 bit architecture, what is the reason can not say.
This architecture was developed by AMD, so sometimes it is called, not to be confused with other 64-bit architectures. - eloisa19 commented on July 12th 19 at 17:05
