[Bug 1584539] Re: 16.04 regression: exceptions in ruby code in plugins have started causing vim to segfault

[Paul White]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. We are sorry that we do not always have the capacity to
review all reported bugs in a timely manner.

Ubuntu 16.04 (xenial) reached end-of-standard-support on April 29, 2021.

I'm setting the status of this bug to 'Incomplete' as it's not seen any
activity for some time. If this is still an issue while using a
currently maintained release of Ubuntu then please let us know which
one(s) otherwise this bug report can be left to expire in approximately
60 days time.

** Changed in: vim (Ubuntu)
       Status: New => Incomplete

Title:
  16.04 regression: exceptions in ruby code in plugins have started
  causing vim to segfault

Status in vim package in Ubuntu:
  Incomplete

Bug description:
  In 14.04, an exception in the ruby code of a plugin caused the error
  to be printed to stderr, after which vim would launch, skipping the
  offending plugin:

    Error detected while processing /mnt/terra/home/simon/dev/vim-livecoding/plugin/livecoding.vim:
    line   37:
    NameError: undefined local variable or method `undefined_method_causing_an_exception' for main:Object
    Press ENTER or type command to continue

  But in 16.04, the same thing causes vim to segfault:

    Vim: Caught deadly signal SEGV
    Vim: Finished.
    Segmentation fault (core dumped)
