@mbrechtold, yeah, please share the dump. From the BT it seems to be a similar subtle issue you've reported last time. Is opcache involved here?

Thanks.

Hi,

thanks for sharing the dump again. Unfortunately digging into it didn't bring much, seems more debugging is required. From what I can tell now, the crash happens somewhere around Application\Controller\SublicenseController, but many useful infos are optimized away. It would rock if you could play with this so we maybe could come to a deeper location.

Thanks.

btw this could just have been fixed with c16dcd3a, maybe you could check this.

Thanks.
