Segmentation fault in Symfony’s cache clear CLI command

So….this happened:

$ app/console --domain=myDomain cache:clear
Clearing the cache for the dev environment with debug true
Segmentation fault

Apparently Segfaults happen, when a process tries to access a portion of RAM that’s already used otherwise.

Removing the app/cache folder contents fixed the problem:

$ app/console --domain=myDomain cache:clear
Clearing the cache for the dev environment with debug true
Done
