RuntimeException error on update

[zeckdude]

I tried to run a composer update and I receive the following error:

[Symfony\Component\Process\Exception\RuntimeException] The process has been signaled with signal "11".

I have removed all other packages and have figured out it has something to do with your package and perhaps a conflict with another package that was updated during the update.

Do you have any idea why that error message would appear and how to fix it?

I figured out that there is conflict with your package and this package: "laravel/cashier": "~2.0"

How can I figure out what sort of conflict is causing the error to occur?
