Bug #74000 [NEW]: Segfault in zm_deactivate_user_filters

From: aseering at gmail dot com Operating system: Linux - Ubuntu 16.04 PHP version: 7.0.15 Package: Reproducible crash Bug Type: Bug Bug description:Segfault in zm_deactivate_user_filters Description: ------------ I use the AfterLogic Light webmail program, written in PHP. When I send an e-mail, PHP segfaults. This is 100% reproducible; the stack always looks essentially the same. I unfortunately don't have a tight reproducer at this time. I do have a core file, and have posted a stack trace. I can look into potentially coming up with a tighter reproducer if what's going on is not apparent from the core file or stack trace.
