Per POSIX this case should produce +0, but buildfarm member fossa (with icc (ICC) 19.0.5.281 20190815) is reporting -0. icc has a boatload of unsafe floating-point optimizations, with a corresponding boatload of not-too-well-documented compiler switches, and it seems our default use of "-mp1" isn't whacking it hard enough to keep it from misoptimizing the stanza in dpow() that checks whether y is odd. There's nothing wrong with that code (seeing that no other buildfarm member has trouble with it), so I'm content to blame this on the compiler. But without access to the compiler I'm not going to guess at what switches might be needed to fix it. For now, tweak the test case so it will accept either -0 or +0 as a correct answer.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication thread/ A thread-safety-testing utility used by configure
