Description

Looks like pg-1.6.2
https://github.com/ged/ruby-pg/tree/c75ed8da19c356b52d83da2627295760780d3d36
testsuite began to segfault, especially the following

#!/bin/bash

export PGPORT=54321
export RUBY_PG_TEST_DIR=/builddir/build/BUILD/tmp
export RUBYLIB=/builddir/build/BUILD/rubygem-pg-1.6.2-build/pg-1.6.2/usr/share/gems/gems/pg-1.6.2/lib:/builddir/build/BUILD/rubygem-pg-1.6.2-build/pg-1.6.2/usr/lib64/gems/ruby/pg-1.6.2

# The above path should be replaced properly

rm -rf $RUBY_PG_TEST_DIR

exec ruby -S --verbose \
	-r ./spec/helpers \
	rspec -f d \
		spec/pg/connection_spec.rb -E '' \
		--seed 1

segfaults like below (will write later)

It seems that segfaults began to happen between
706d80830b9f0a5a2eac66251d1417abb2ff143c (no problem) and d7e55f84f2bd62d302b29513d4c4dc8ae9aef96f (segfaults)

Tried with edca81a1bb72a9dc54a37766d2c80790dec13884 it still segfaults.

Note that ruby-pg compiled with 706d80830b9f0a5a2eac66251d1417abb2ff143 does not segfault
with ruby edca81a1bb72a9dc54a37766d2c80790dec13884 , so I suspect that there is something wrong with
"inlined" function or so.
