Magento – Error Segmentation fault (core dumped) in Magento 2

I have installed Magento 2 in my Windows Local Machine using WAMP 3.0.4. I tried making a simple "Hello World" module. But, when I tried to run the module, I get the following error:

Please upgrade your database: Run "bin/magento setup:upgrade" from the Magento root directory.

The following modules are outdated:

Censere_HelloWorld schema: current version – none, required version – 1.0.0
Censere_HelloWorld data: current version – none, required version – 1.0.0

But when I tried to run the command php bin/magento setup:upgrade in Cygwin, it throws me the error:

Segmentation fault (core dumped)

What could I do?

Thanks.
