Re: [BUG] Org-mode 9.6 parallel build issue [9.6 (N/A @ /usr/share/emacs/site-lisp/org-mode/)]

Hi Ihor!

> Cannot reproduce.

I think this is more likely to happen to users who actually compile on 
boxes with very high CPU/thread count.
A common user with ~8 threads probably will not hit this issue
(I also could not reproduce this on my 4c/8t daily-driver).
Regardless if a common users is likely to hit those errors, they could 
indicate that there are some bugs in the Makefiles.

There are logs in the bug report on the Gentoo Bugzilla,
from the bug I had already mentioned:
https://884243.bugs.gentoo.org/attachment.cgi?id=839581
and from the one occurring with the documentation generation process:
https://884403.bugs.gentoo.org/attachment.cgi?id=840181

Not much, it is just a wrapper for make that adds the MAKEOPTS variable 
from the Portage configuration.
You can see the exact make command in the logs, that is:
- for bug 884243: make -j62 ORGVERSION=9.6 
datadir=/usr/share/emacs/etc/org-mode
- and for 884403: make -j63 pdf card

Thanks for taking a look at it!
