>Description:
With firefox-71.0 and adobe-flash-player-32.0.0.303,
/usr/pkg/lib/firefox/plugin-container binary dumps core
on executing adobe-flash-player plugin binary via nspluginwrapper.

- firefox 71.0 plugin-container also dumps core on NetBSD/amd64 9.0_RC1
- it works fine with the previous firefox-70.0.1 from pkgsrc-2019Q3

>How-To-Repeat:
'pkg_add firefox adobe-flash-player' and browse flash pages,
for example:
 https://helpx.adobe.com/flash-player.html

>Fix:
Not yet.

Note building firefox with "debug" or "debug-info" options fails
on NetBSD/i386 9.0_RC1 due to memory (maybe VA space) shortage..
