OGRE 1.9+Win7+OpenGLRenderer: Memory leak

Post by only_a_ptr » Tue Aug 15, 2017 3:21 pm

Hello.

I'm using "Windows Application Verifier" and I'm getting a debug break with "memory leak" error report when stepping over the following line: https://bitbucket.org/sinbad/ogre/annot ... rt.cpp-524

This is the critical part of AppVerifier output:

Code: Select all

<avrf:logEntry Time="2017-08-15 : 15:19:55" LayerName="Leak" StopCode="0x900" Severity="Error">

Background of my research: https://github.com/RigsOfRods/rigs-of-rods/issues/1366 - multiple people (mostly Linux users) experienced heap problems recently.

Test system:
-- Windows7 Professional 64-bit, service pack 1
-- Visual Studio 2015, version 14.0.23107.0
-- 16GB RAM
-- Graphics card: AMD RadeonHD 6350 (driver version: 8.922.0.0)
-- Dependencies built from: https://bitbucket.org/cabalistic/ogrede ... 0f9d04.zip
-- OGRE built from: HG_REPOSITORY https://bitbucket.org/sinbad/ogre HG_TAG v1-9 (from our CMake scripts at: https://github.com/RigsOfRods/ror-dependencies)
-- Test application = my OGRE testbed project: https://github.com/only-a-ptr/ogre-imgu ... pt-testing

OGRE + dependencies were built on the same machine, I'm attaching CMake files.

I'd like to research further but I won't have time until 27.8.
