Bug: C++ timestamp tests intermittently fail

Reported by: rleigh Owned by: rleigh
Priority: major Milestone: 5.1.2
Component: Bio-Formats Version: 5.1.0-m1
Keywords: cpp Cc: sbesson
Resources: n.a. Referenced By: n.a.

Description

18: [ RUN      ] TimestampVariants/TimestampTest.StreamOutput/3
18: /opt/hudson/workspace/BIOFORMATS-5.1-release-cpp/BUILD_TYPE/Debug/CXXSTD_AUTODETECT/OFF/label/cod/source/bioformats-5.1.0-m5/cpp/test/ome-xml/timestamp.cpp:127: Failure
18: Value of: params.output
18:   Actual: "2003-08-26T22:46:38.762000Z"
18: Expected: os.str()
18: Which is: "2003-08-28T01:46:38.762000Z"

This is out by -27h -- it's not something like a DST or timezone-related inaccuracy. And it's not consistent; it's only occurring intermittently which is quite odd for something which should be completely deterministic.

  • Milestone changed from 5.1.1 to 5.1.2

Moving to 5.1.2; not enough time for 5.1.1.

Not reproducible with 1.55 (FreeBSD) or 1.58 (MacOS) or 1.55 (Ubuntu 15.04).
However, it is reproducible with 1.54 or 1.55 (Ubuntu 14.04). So it might be a Boost bug, but might equally be a libc bug.
