How to do core dumps when using FrankenPHP on Docker

[andersonpem]

I have a really nasty issue that is happening to me with an absurd amount of memory

malloc(): unaligned tcache chunk detected

memory allocation of 8317990652097027172 bytes failed

This is not memory, it's probably a corrupt address.
Is there a way to enable core dumps so I can inspect what in the world is causing this? I suspect it might be a PHP extension. Opcache is disabled. Xdebug is disabled.

Some of it is explained here. You can also install the PHP debug version by doing this in your Dockerfile. Could you also try if this still happens in v1.9.1 or provide a reproducer? If 1.9.1 doesn't fix it.and it's happening consistently, it's likely connected to an extension you are using.

Will check if it still happens with 1.9.1
