VBufBackend_t: hook WM_DESTROY and call renderThread_terminate if the window being destroyed is the root of a backend. This is necessary when the destroy winEvent is not fired (e.g. Adobe Flash). Re #5367.
This fix definitely covers one possible crash. However, some users are still reporting crashes even with this fix, so leaving open for now. |

@jcsteh Does #5367 (comment) mean that this issue has only been solved in part? If so, I would be interested in hearing from @derekriemer and others if they still experience Flash crashes with NVDA running. Regardless, it should be noted that Flash shall be discontinued by Adobe by the end of 2020. |
I just wonder though, whether web sites will all be using html 5 instead of
flash by then. I suspect not.
I know a lot of sites, often those like paypal and e commerce sites for
credit card entry etc, still prompt for flash if its not enabled and can be
very hard to navigat either with it on or off.
Not had outright crashes for some time, but occasionally they do just tell
me I'm out of date despite having the latest version of flash.
Quite how one can do much at the screenreader end I don't know.

We haven't had solid reports on Flash crashes for a while. Also, #6885 might have fixed some potential issues here. With the demise of Flash, this is getting less and less relevant (and harder and harder to test). Closing as works for me, but we can reopen if someone can reliably reproduce this. |

I am using Firefox 40.0.3 and shockwave flash 18.0R0 with NVDA master 11410. In certain websites Firefox shows a erorr message, that flash addon crashed.
For example on this site:
http://www.rtvs.sk/radio/archiv/1122
(sorry for slovak site, I can not find something useful in english).
When I disable NVDA and refresh the page, everithing works. I tryed run NVDA without addons and Firefox in safe mode but result is the same.
here is the log:
