Hi, We're facing a Segmentation fault with ruby 2.7.8 and pg 1.5.3 in a rails application (v6.1.7). This is sometimes happening in CI. It is sometimes reproducible locally but I haven't found the right conditions to always reproduce the issue.

Stack trace

Actual failing code

class ExecuteSQLFile
  include ActiveRecord::ConnectionAdapters::Quoting

  def initialize(filename)
    @filename = filename
  end

  def result(params = {})
    pg = ActiveRecord::Base.connection
    @type_map ||= PG::BasicTypeMapForResults.new(pg.raw_connection)  <---- failing here
    result = pg.execute(query % quoted_parameters(params))
    result.type_map = @type_map
    result
  end
  ...
end

Is there anything I can try to fix it ?
Maybe the answer is to just upgrade ruby version.

[EDIT]
Also seeing the issue with ruby 3.0.6
The stack trace has more details with this ruby version.

I can't provide much information for this, but we're seeing a crash with ruby 2.7.8 on windows with the PG gem, but the only thing windows is reporting about the error is error code -1073740940, which I think is a heap stack corruption.

Both ruby versions crash on PQisBusy. This function has a single argument, which is the PQconn pointer. For me it looks like the PQconn was released for some reason or points to some invalid memory for some reason. I don't have an idea why this should happen.

The only other reason for a crash, I could imagine, is that the PQconn is used concurrently by two threads, but that should lead to some invalid message warnings in addition to the segfault.

It could help to reproduce the segfault in a gdb session. On modern Linux distributions like Ubuntu-23.04, gdb asks for download of debug symbols of system libraries, so that we could see, within which function and source line libpq crashes.

Beside this I don't have a good idea for now. So far it's the only bug report of this kind.

FYI, you can also use ?gssencmode=disable in the connection url param to disable this, or set gssencmode: disable right in config/database.yml.

Edit: while this helped, it didn't fix it in all cases
