Corona Standalone fails to save image after 2 mins of rendering

[ohsnapitsjoel]

After rendering in progressive mode for over 2 mins, upon closing Corona Standalone the image is not auto-saved to the output directory.  The Blender exporter also seems to hang, thinking Corona is still running; it doesn't seem to be getting a return code from the terminated process.  I imagine these are probably related?

Is there a scene for this bug?

here's scene > https://www.sendspace.com/file/95e77o
Description:
Basic scene (cube, plane, sun, sky) with buggy settings.
After rendering for 2 min. one of cores stops rendering, rest of cores continue (75%).
Stoping only stops Rendering counter, yet cores are still used and continue calculating rays.
Closing Corona engine stops rendering, yet doesn't stop the process (still on in WinTaskManager - 0%).
ohsnapitjoel posted on BA forums the reason is using Progressive (renderer) with HD Cache (GI solver).
After testing other combinations (renderer+solver) proved there's bug, 'cuz they work without hanging.

There is error in the export... Are you using the latest (2014-15-09) corona version?

Hi, sorry for late reply.
I am using ohsnapitjoel versions:
Corona SA: https://www.dropbox.com/sh/zhle8shcnn9cgd8/nKknGftJ6p/Corona%20Standalone
Exporter 1.9.2: https://bitbucket.org/ohsnapitsjoel/render_corona/downloads

I think he uses latest SA version posted here: https://www.dropbox.com/sh/kgzu0cqy903ygmb/AAByhDIoH1GiSVBcV9eC2MDfa/!Standalone/2014-09-15?dl=0 (yup, done file comparison; files are same)

Edit / 01.01.2015:
Unusable anymore. Thank you for time shared.
